Electrical data
Supply (terminals 51, 52): U = 19.2 ... 31.2 Vdc.
Status-Relay output (terminals 53, 54):
U ≤ 32 Vac or 32 Vdc, I ≤ 0.5 Aac or I ≤ 1 Adc respectively.
If the repeater is installed outside the hazardous area, the following data for the relay contacts apply: U ≤
110 Vdc or 125 Vac, I ≤ 0.3 Adc or I ≤ 0.5 Aac respectively.
Outputs (terminals 41, 42 resp. 43, 44): I = 4 - 20 mA.
For all circuits above: U
m
= 253 Vac (max. frequency 400 Hz).

Both circuits of one channel are not used simultaneously.
The input circuits of both channels are infallibly galvanically isolated from each other and from the non-
intrinsically safe supply and output circuits.
Combination of current loop input of channel 1 and current input of channel 2, where terminal 13 is
connected to terminal 21:
