General Information on Relays 

There are numerous applications for relays in Telemetering Technique. They are necessary for the 

conversion of pulses from one form into another (e.g. S0 into bipolar current), for multiplying individual pulses 

and distributing them to multiple receivers (customer / public utility company) or for pulse value modulation 

(150 pulses / kWh to 100 pulses / kWh). Some of our relays offer all three applications combined into one 

unit. 

Available Housing Types

The following criteria should be considered when choosing among the different types of relays: 

Transmission Distance 

The S0-interface is relatively unproblematic and meant for shorter distances. Longer distances are better 

bridged with wipe pulse- (115 or 230V�) or bipolar current relays (� 24V=). 

Auxiliary Power Supply 

If an auxiliary power supply is available, then it is best to use relays with wear-resistant electronic contacts. 

Relays that do not use an auxiliary power supply have limited uses (passive wipe pulses- and outputs or 

bipolar current with doubling of the interpreted value) and only allow for low pulse frequencies (up to about 

5Hz). 

Type of Construction 

The 7PA.../7PW…/KLN/ITR-modular relays are recommended if wall or top hat rail installation is possible. 

They are both compact and relatively inexpensive and usually provide the most practical alternative. 

Installation Positioning 

Mercury-wetted contacts can only be considered if vertical installation of the relay can be assured. Electronic 

relays can be installed in any position. 

Output Contacts 

The best results are provided with wear-resistant electronic contacts, but hey are only available as make 

contacts at the present time. If double-throw contacts are required, then the mercury-wetted reed contacts 

provide the only alternative. These contacts are increasingly disapproved of, because of the negative 

environmental impact. 

Galvanic Isolation 

If the outputs have to be isolated from each other (e.g. to prevent problems from the customer side from 

traveling to the public utility net), then wipe pulse outputs should be selected. Relays with bipolar current 

outputs normally have only one power supply, meaning that the outputs cannot be isolated from each other. 

Pulse Frequency 

All relay types can be used up to about 5Hz. For higher frequencies the electronic relays with S0 inputs, and 

wipe pulse or bipolar current outputs should be used. Bipolar current inputs internally produce a 90ms pulse 

with every pole change and, because of this, must be specially made with a shortened pulse length if they are 

to be used here. Wipe pulse inputs must be excluded here, because of the long debounce time required when 

alternating current is used. 

Pulse Value Modulator 

The values of pulses can be changed using a pulse value modulator. 

Example: A meter delivers 75 pulses per kWh. Each pulse is evaluated as 0.01333 kWh. When a relay with a 

pulse value modulator is added, then the resulting pulses can be given values of e.g. 0.01 kWh, which can be 

processed by adding simple tariff units to the system. 

Pulse values can be set directly on our tariff units, making pulse value modulators unnecessary. 

Pulse Timer 

Some relays have built-in "Timers", that make the output pulse length independent of the input pulse length. 

They typically produce 90ms pulses, which is important when the 5Hz-Technic is used. Other pulse values 

are available upon request.

Pulse forms 

Inputs 

IEI Pulse Input - Inductive 

Inductive pulse inputs, together with an L.C. combination that is built into a meter, form an oscillating circuit. 

Pulses are generated when this circuit is periodically dampened by a wing wheel that is installed on the meter 

axis. 

IEI Modules are active inputs and supply the detectors in the meter. The signal detector must be isolated 

(isolated from all ground and all potential voltage connections). 

Because the highly sensitive oscillating circuit can be affected by a wire's inductivity and capacity, and by the 

influx of foreign signals in and around a wire, the secure function of this input can only be assured with a wire 

length of up to 30cm. For this reason inductive pulse detectors are, for all practical purposes, no longer used.

IED Pulse Input - Bipolar Current 

Bipolar current inputs are passive inputs, meaning, that they are supplied by the pulse giver. This means that 

they are isolated elements. Bipolar current pulses are direct current pulses that change polarity with each 

pulse. Each 0V-Line cross-over will define a pulse. This can also be accomplished using a constant (not in 

pulse form) direct current. The polarity must be changed, thus providing the necessary 0V-Line cross-over, 

for each meter pulse. 

24VDC current is usually used, but may also vary from between 19VDC and 60VDC. The input current drawn 

by our electronic bipolar current inputs is less than 2mA (with 24VDC). 

Since each meter pulse implies an input-polarity change IED modules internally produce a complete 90ms type 

pulse for each valence change. This must be taken into account in coordination with the maximum pulse frequency 

(< 7Hz). IED modules that produce 20ms type pulses are also available. They can be used with a pulse frequency 

of up to 30Hz. 

Since bipolar current transmission is not easily interfered with, they are highly recommended for use with long 

transmission distances. Depending on the particular circumstances (other inductive sources in the vicinity, 

very long transmission distances, etc.), shielded cable or cable with larger cross section might still be 

recommended, if this is possible.

IES S0 Pulse Input 

S0 inputs are active elements. They supply the pulse detector with a signal, but also with an auxiliary power 

supply. S0 elements can contain a complete electronic package without the complication of an extra power 

supply connection. The S0 specifications comply with DIN 43864 current and voltage limits. S0 inputs must 

be able to deliver, at least, a 10mA current when loaded with a resistance of 800� (for supplying the pulse 

detector). They must also be able to recognize a current of 2.2mA as an "OFF" signal. They are not allowed 

to deliver more than 27VDC. 

For these reasons, S0 inputs are well suited for use with simple isolated contacts, passive optic coupler 

elements and transistor elements. 

They are often used for control connections (tariffs, resetting, etc.).

265VAC/DC. The maximum pulse frequency is 10Hz and the current draw is less than 10mA. 

A pulse length of � (a constant current) is also allowed. These IEW modules are also well suited for use with 

control connections.

IAD Pulse Output - Bipolar Current 

Baer Bipolar Current Outputs deliver a constant 24VDC, but with a polarity change with each meter pulse. 

This provides what amounts to an extra power supply, that is usually used to supply power to other Bipolar 

Current Outputs from the same unit. This means that individual connection terminals from different Bipolar 

Current Outputs must be isolated from each other, even if other equipment is connected in-between these 

terminals. Any Bipolar Current Inputs that come afterwards, must be isolated.

switching frequency, making them ideal for high pulse frequencies.

IAW me. Pulse Output - Wipe Pulse (Relay Contact) 

Mechanical relays offer, at present, the only practical possibility of constructing transmission relays 

(IEW�IAW or IED�IAW with pulse value doubling) that do not require an auxiliary power supply. They are 

also the only possibility for double-throw contact outputs. 

Mercury-wetted contact relays (HG) are often selected for pulse transmission lines, since they offer the 

longest operational life (>10 9 switchings), meaning that only they can assure decade-long service with a pulse 

frequency of 5Hz. Mercury is used as a wetting material for the switch contacts to eliminate contact bounce 

during switch actuation.

This relay is important for galvanic isolation, conversion and multiplication of both pulse circuits and signal 

circuits in telemetering, summation telemetering and maximum value monitoring installations. 

It has one input and four galvanic isolated outputs. An on-coming signal can be used for adapting the pulse 

value modulation using an optional electronic gear system. Their ratios are set in tandem with programming 

switches. 

The electrical connection is made using a 32-pole blade plug that complies with DIN 41612, Form D.

The pulse ratio can be calculated using the following formula: R � � � 

Re D 1 

Notice: Numerator (N) and Denominator (D) must be whole numbers between 1 and 255 (pulse ratios larger 

(faster) than 1-to-1 cannot be used). The modulated values that will be transmitted by the output, have a 

basic pulse length of 90 ms, and are independent of the length of the signals on the input.
