Signaling contact
Information on the signaling contact
The signaling contact (relay contact) is a floating switch that signals faults by breaking the
contact. The signaling contact is connected to a 2-pin plug-in terminal block.
NOTICE
Damage due to voltage being too high
The maximum load on the signaling contact is 24 VDC and 100 mA (safety extra-low
voltage (SELV)).
Higher voltages or currents can damage the device!
