Relays Series 7FR..     

    Technical Partition 3    


7FR5067
7fr5067

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.

Inputs: 1 IEW 60V - 110V or 220 / 230V@ (rearangeable)
1 MPE 60V - 110V or 220 / 230V@ (rearangeable)
Outputs: 1 galvanic isolated optic-electric pulse output for wipe pulses.
1 relay contact for MPA, Operational life ca. 5 105 switchings
Pulse Length: ca. 90ms (only electronic output)
Pulse Frequency: fmax.= 5Hz (only electronic output)
Load Rating: Max. 250V~ and max. 0,1 A
(electron. residual voltage at 50mA < 3.5V residual current < 0.1mA at 230V)
Auxiliary Power: 115V/230V~ (change over)
Power Consumption: ca. 1,5VA
Display: pulse display using 2 LED's
Order-Number: 03874

(umschaltbar 115/230V) = 115/230V change over

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
active, for acceptance of pulses from an S0 interface (complying with DIN 43864, pulse length > 30ms)
or from an isolated contact.
Outputs: 2 electronic wipe pulse output
1 measuring period output (relay 10A / 2500VA),
Operational life ca. 5 105 switchings
Auxiliary Power: 115V / 230V~ (change over)
Power Consumption: ca. 1,5VA
Display: pulse display using 4 LED's
Order-Number: 03750

7FR5072
7fr5072

(umschaltbar 115/230V) = 115/230V change over

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.

Inputs: 3 S0-Input
Output: 3 mercury-wetted maker contacts, each rated at 230V/100mA,
Cos φ(phi) = 1
Operational life: ca. 5 109 switchings
Auxiliary Power: 115V / 230V~ (change over)
Power Consumption: ca. 1,5VA
Display: pulse display using 4 LED's
Order-Number: 04547
