The 7FR5067 auxiliary relay helps
in galvanic isolation and amplification of pulses and signal circuits
in Telemeter-, Summation telemetering- and maximum value monitoring
installations.
This relay has two inputs. From Input 1 the pulses can be directed to
an electronic pulse value modulator with binary organizable program
switches.
Control signals (i.e. high-/ low tariff or tm (measuring period length)
will be transmitted at a 1:1 ratio from Input 2.

The 7FR5071 auxiliary relay helps in galvanic isolation and
amplification of pulses and signal circuits in Telemeter-, Summation
telemetering- and maximum value monitoring installations.
This relay has three S0 inputs, two electronic wipe pulse outputs, one
measuring period output (relay) and one pulse value modulator.
Assignment of the two S0 inputs and the electronic wipe pulse outputs
is selectable using jumpers. The values that go through the electronic
pulse value modulator have a wipe pulse function on the output. Their
pulse length is settable to 20 / 90 / 200ms, independent of the signals
coming from the S0 inputs.

| Inputs: |
3 × S0-Inputs

The 7FR5072 auxiliary relay helps in galvanic isolation and
amplification of pulses and signal circuits in Telemeter-, Summation
telemetering- and maximum value monitoring installations.
This relay has three S0 inputs, three mercury-wetted wipe pulse outputs
and one pulse value modulator.
Assignment of 2 of the S0 inputs to the wipe pulse outputs is
selectable using jumpers.
Pulses can be adapted by directing them from the input, through an
electronic pulse value modulator, with binary organizable program
switches.
The values that go through the electronic pulse value modulator have a
wipe pulse function on the output. Their pulse length is settable to 20
/ 90 / 200ms, independent of the signals coming from the S0 inputs.
