Signaling contact

Information on the signaling contact

● The signaling contact is a floating switch with which you can output the mode.

The signaling contact must be operated within the range of the operating voltage.

When the bypass relay is in bypass mode, it closes the signaling contact. If the bypass

relay is in normal mode, the signaling contact is open.

● The signaling contact is connected using a 2-pin plug-in terminal block (spring-loaded

terminal). The terminal block ships with the device.

● To wire up the signaling contact, use a copper cable of category 18-12 AWG or a cable

with a cross-section of 0.75 to 2.5 mm

NOTICE

Damage due to voltage being too high

The signaling contact can be subjected to a maximum load of 100 mA (safety extra low

voltage SELV 12 VDC / 24 VDC / 48 VDC).
