3.4.4 Isolated Optocoupler Outputs Connector
The transistor connections, collector and emitter, of the two optocoupler outputs are
galvanically isolated from the reader electronics and brought out on connector X6
without any additional circuitry. The outputs must therefore be powered by external
supplies.
The outputs are designed to switch resistive loads only.

Note:
If the connecting cable is longer than 3 m you must use shielded
cable.
CAUTIONS:
Reversing the power supply wires may destroy the device.
