No matter what combination of process signal 

I/O, power input and mounting configuration 

you need, M-System can meet your requirements 

when others can't. Just what you would expect 

from the world's largest supplier of 

high-performance interface solutions. 

Count On Us for Quality & Reliability 

Quality: M-System delivers more than 500,000 I/O units (300,000 units of signal conditioners) every year, 

and we are very proud of our manufacturing and quality control process certified by ISO 9001. 

Reliability: M-System does not easily stop manufacturing products once released in the market, unless we are 

able to supply other products of equal or better quality to replace with, because we believe it is a very 

important responsibility as a leading manufacturer in the world to continue to serve people who maintain the 

performance of process control systems. 

Count On Us for Fast & Precise Delivery Time 

The standard manufacturing lead time for most M-System's signal 

conditioners is 5 days. But more than quarter of the total shipments 

are delivered in shorter lead time, and Quick Service Center expedites 

more than 500 orders every month on the same day or the next day 

after ordered. Do not worry too much about the standard delivery. 

Just let us know 'When' you need a signal conditioner. Once a 

delivery date is promised, you can of course count on us to deliver the 

products precisely on time. 

Meeting with Modern Industrial Trends

18 mm (0.71”) thin profile DIN rail mounting 

M-System’s M3L Series is a DIN rail mounted, universal input 

transmitter with 1500 Vac isolation. 

Ideal for Spare Parts Stock Reduction Programs, the M3L Series 

supports two methods for configuring the unit. The unit’s DIP 

switches/control buttons simplify in-field configuration without 

using a PC. When identical multiple configurations are required, 

save yourself some time downloading the setting from PC 

software. 

M3L Series is your safe bet when you are not sure of 

your final I/O signals. 

Typical applications include eliminating ground loops in 

temperature measurement applications and providing an isolated MODEL FUNCTION 

interface to data acquisition and control systems. M3LU Universal (DCmV, V, mA, T/C, RTD, Pot)

B3 Series 

DIP-Switch Configurable Two-wire Transmitters 

Input type and range selectable with the internal DIP switches and fine 

calibration using the front potentiometers. 

Wide supply voltage range 12-45 Vdc 

Eliminates noise and prevents ground loops with 1500 Vac isolation between 

input and output 


M-System’s B3 Series are DIN rail mounted, input configurable 

two-wire transmitters with 1500 Vac isolation between input and 

output. 

The input type & range are easily programmable with internal 

DIP switches and front potentiometers, not needing any special 

computer knowledge to program. 

For example, after setting the internal SW1 and SW2 for 

selecting an overall range, gain and offset, using a DC input 

simulator as a reference, the B3FV could be adjusted to 0 to 10 

V range by simply applying desired minimum and maximum 

input levels and turning the respective front potentiometer. 

Typical applications include eliminating ground loops in temperature, 

flow and level measurement applications and providing 

an isolated interface to data acquisition and control systems. 

For the most basic isolation applications, the Model B3VS/2 

dual channel isolator is an economical solution. The B3VS/2 

houses two transmitters in the series’ standard enclosure, 

accepting and providing independently isolated 4-20 mA 

signals.

M-System’s Models B6U and B6U-B accept a wide variety of inputs including thermocouples and RTDs as well as mV, resistance and 

potentiometer sensor types. This universal two-wire transmitter reduces component costs while meeting the requirements of hazardous 

applications. They provide signal isolation to output a proportional 4-20 mA signal. 

Both models have the HART capability which allows users a flexibility to program the modules either via hand-held communicator or via PC. 

Input sensor type, temperature range and other items including HART properties are programmable. Additionally, users’ own temperature 

calibration tables can be used. This feature makes the B6U and B6U-B the most universal temperature transmitters. 

Optional highly legible LCD display indicates input signal in engineering unit and the transmitter status. The module is also used to configure 

the transmitter and can be removed when not used. 

The B6U designed for intrinsic safety and the B6U-B including the explosion-proof (flameproof) enclosure (NEMA 4X, IP65) are most suitable for 

use in an explosive atmosphere in chemical and petrochemical industries. A pipe mounting bracket is optional for the B6U-B for easy installation.

SMOOTH PUMP OPERATION 

AS4T 

We are trying to control the level of liquid in a tank by staging four pumps that are 

connected in parallel (see figure). However, the continuously changing liquid level 

causes pumps to cycle ON and OFF sporadically around the setpoints. How can we solve this 

problem? 

You will need to set a deadband (hysteresis) for each pump’s control setpoint. 

A With or dinary limit alarms, you might have to set two trip points for each pump to 

accomplish this result. The AS4V can be field programmed to eliminate the unwanted pump 

cycling, giving you consistant pump operations and control.

M-System’s model 53U is a 96-mm-square Multi LCD Power Monitor mounted on a panel surface. 

One model can be used for single-phase/2-wire and 3-wire, three-phase/3-wire and 4-wire systems. Users can freely choose and 

program major variables in heavy-current power systems, such like AC voltage/current, active/reactive power, power factor, AC 

frequency deviation, apparent power, active/reactive energy and up-to-the-31st harmonic distortions. 

Measured variables also include the maximum/minimum/average values, in total of 500 types. Up to 1800 patterns of display 

combinations are available. 

All measured variables can be transmitted to the host PC via RS-485/Modbus RTU. Conversion factors, system configuration, interval 

times are programmable using the front keys, or the PC Configurator Software locally or remotely. Measured values, counter values, 

display mode, setting data are stored in the non-volatile memory at the power off. 

An open collector output can be used for energy count pulse or limit alarm trip. Pulse rate for energy count can be specified. The 

contact output can be simulated for testing the connected device. 

External open collector input is typically used to reset energy count memory. The signal can be also monitored at the host system via 

Modbus, so that the host can start/stop monitoring according to ON/OFF status of a load (e.g. motor running or not).

MD7 Series 

Ultra-Slim Lightning Surge Protectors 

High-density mounting with 7-mm wide modules 

Excellent protection by multi-stage SPD 

Max. discharge current 20 kA (8/20 µsec.) 

Floating mode for the shield to avoid ground loops 

DIN rail mounting / grounding 

Loop disconnect fuse (option) 

FM intrinsically safe (pending) 

The MD7 Series is a new family of surge protectors offered from M-System, 

specialist of signal conditioning who knows about a variety of electronic 

devices interfacing field sensors and control rooms. 

The MD7 surge protectors are multi-stage SPD, which, in addition to the 

discharge element at the first stage, provide an extra protection by a series 

resistance with diodes to limit current flow. The maximum discharge current 

is up to 20 kA to further enhance its performance. 

All MD7 products have an independent set of shield terminals, therefore it is possible to choose ‘Floating’ or ‘Grounding’ shield 

terminal to suit users’ application needs. Floating mode is especially effective to prevent a ground loop. 

The MD7 surge protectors are designed to earth ground through DIN rail, and by connecting the rail to the earth, they are 

automatically grounded when they are mounted on it. No need of cross wiring. 

Model MD7ST has an optional ‘Loop Disconnect Fuse’ function to conveniently separate the protected device from the power bus to 

protect others when it has failed in shortcircuit mode.

NEW 

The MD7 Series are designed for multi-point, ultra-high-density installation. DIN rail mounting/grounding and slanted terminal block 

help installation and wiring work in such tight space. 

When the DIN rail is grounded at single point, surge protectors mounted on it are automatically connected to the earth. There is no 

need of cross-wiring individual module. 

Thanks to the terminal blocks slightly slanted forward, access from the front side to the terminals is easy even after the protectors are 

mounted on the rail.

Future Plan 

Future Plan 

HIGH PERFORMANCE 

The multi-stage protection combining discharge elements at the 

first stage and the series resistances and diodes ensures to limit 

the current flow. 

The maximum discharge current capacity is as high as 20 kA 

for an impulse wave of 8/20 microseconds. The MD7 Series 

are tested according to IEC 61643-21 standard to be suitable 

for categories C1, C2 and D1. C1 category requires the surge 

protector to withstand 300 times of average induced surges, 

C2 to withstand 10 times of strong induced surges generated in 

a harsh environment without electromagnetic shielding. D1 

category is tested by two direct hits.
