Wiring and connecting relay outputs
Wiring
The USS, PROFIBUS and PROFINET modules have 2 relay outputs (NO contacts).
Maximum voltages of 42.0
V (peak value, ≙
29.6 V
rms
in the case of sinusoidal voltage (SELV
acc. to EN60950-1)) may be applied to the relevant module.
Contact rating of the relay outputs:
●
DC max: 30 V DC, 500 mA
●
AC max: 29.6 V AC, 500 mA, sinusoidal (limited due to the fact that only SELV is
permissible on the module)
The matching 4-pole mating connector (PHOENIX MC1.5/4-ST-3.81) with the screw
terminals is delivered along with the module (plugged in).
The pin assignments are:
