    Technical Partition 2    


7FR5043

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

The 7FR5043 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 one S0 input and three galvanic isolated outputs. The in-coming pulses and signals appear with a ratio of 1:1 on the outputs, if they are intercepted before they reach the value modulator. The inputs can be guided through an electronic value modulator using a jumper, if pulse value modulation is necessary. The outputs will then have a basic wipe pulse function with a pulse length of ca. 90ms (other pulse lengths are available upon request), independent of the conditions on the S0 inputs.

Inputs: 1 S0-Input
Outputs: 3 galvanic isolated optic-electronic outputs,
max. 230V. / 100mA, residual voltage < 3.5V (100mA)
pulse ratio of 1:1.
wipe pulse function (ca. 90ms) when the electronic value modulator is active
Auxiliary Power: 115V/230VAC (change over)
Power Consumption: ca. 1,5VA
Display: pulse display using 4 LED.s
Order-Number: 03578

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

The 7FR5043i 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 one inductive input (for Siemens contact -3 / -8) and three galvanic isolated outputs. The in- coming pulses and signals appear with a ratio of 1:1 on the outputs, if they are intercepted before they reach the value modulator. The inputs can be guided through an electronic value modulator using a jumper, if pulse value modulation is necessary. The outputs will then have a basic wipe pulse function with a pulse length of ca. 90ms (other pulse lengths are available upon request), independent of the conditions on the S0 inputs.

Inputs: 1 IEI (inductive)-Input
Outputs: 3 galvanic isolated optic-electronic outputs,
max. 230V. / 100mA, residual voltage < 3.5V (100mA)
pulse ratio of 1:1.
wipe pulse function (ca. 90ms) when the electronic value modulator is active
Auxiliary Power: 115V/230VAC (change over)
Power Consumption: ca. 1,5VA
Display: pulse display using 4 LED.s
Order-Number: 04127
