A snap in relay module K1:
Phoenix Contact EMG 17-REL/KSR-120/21 Au
Coil: 96 .. 127 V, 24 kohm
Contact material: 5 mm Au (AgPd60)
Width: 17.5 mm
Assembly: DIN EN 50022 mounting rail
TripCircuitSup200ClosePos
Figure 3.5.2-2. Application example, when one of digital inputs 1…6 is used
for trip circuit supervision. Trip circuit supervision when the circuit-breaker
is closed. The supervised circuitry in this CB position is double-lined. The
digital input is in active state. The value for R1 in this application is 3k3
and 2W. These can be calculated from the resistance and voltage operating
range of the coil of K1 and the tolerance of the wetting voltage.
