Digital inputs
Further, the unit can collect status information and alarm
signals via 3 digital inputs (terminals X2B: 3-5). The three
digital inputs in WIMO use an internal 12 V dc auxiliary
voltage of the unit (terminal X2B: 8).
Potential-free contacts must be available in the protected object
for transferring status information to the unit.
4.4.
Output relay
The terminal is equipped with one output relay.
