CAUTION:
•
The outputs are designed for an input voltage of 12-24 V DC and an input current of max. 20 mA.
•
Polarity reversal or overload of the outputs leads to their destruction!
•
The output is only intended for switching resistive loads.
5.7 Relay Outputs on Connector X4
There are 2 relay outputs (type LRU500i-BD only 1) available at terminal X4 as normally open contacts. With
the LRU500i-PoE, each output is fixed with an antenna. Reading a valid transponder on the internal antenna
affects the relay REL1, reading a valid transponder on the external antenna affects the relay REL2.
