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.
5.5 Relay Outputs on Connector X4
There are 2 relay outputs available at terminal X4 as normally open contacts. Each output is linked fixed with
an antenna. Reading of a valid transponder on the internal antenna will affect the relay REL1, a valid reading
on the external antenna will affect the relay REL2.
