Standard Signal
Measuring Contact
AD-MK 330 GS
Description
The measuring contact AD-MK 330 GS compares the measuring
value applied at the input with the measuring value set at the pushbutton
encoder switch. If the measuring signal exceeds or falls
below the set value, the appropriate output relay reacts to pre-set
function.
As analogue input value all three standard signals (0-20mA, 4-
20mA, 0-10V) are possible without additional commutation. The
critical values are to be set at 0-99% at the front via encoder switch.
The output function 2 max, 2 min or 1 max/min as well as the rest or
working principle of the output relay is also adjustable at the front.
Input, output and the supply voltage are galvanically separated
from each other.
A highly efficient, integrated electronic power pack enables operation
with 20-253 V AC/DC. There is no possibility of cross polarity of
the connection voltage. A high packing density is achieved due to its
narrow build.
Application
Monitoring and signalling of critical values of analogue measuring
signals, as for instance flow, level, temperature, dry operating protection.

Supply Measuring Contact
AD-SMK 330 GS
Description
The supply-measuring-contact AD-SMK 330 GS supplies a 2 or 3
wire transmitter with a DC voltage of 24 V DC, registers and compares
the measuring value of 4-20 mA at the input with the values
set at the touch code switches. If the measuring signal is higher or
lower than the set value, the appertaining output relay reacts to
pres-set function.
The limiting values are set at the front via touch code switches 0 -
99%. The output functions 2 max., 2 min. or 1 max/min as well as
the rest or working principle of the output relay can also be set at the
front side. Input feed voltage, outputs and the supply voltage are
separated from each other galvanically.
Application
Potential free supply of a 2 or 3 wire transmitter with monitor and
signalling of limiting values of analogue measuring signals such as
flow-through, height levels, temperatures, dry run protection,
amongst others.
