Power supply
The 3-pin socket for the external 24 VDC power supply is located on the top of the module.
The reader is supplied with voltage via this power supply. The matching plug with screw
terminals ships with the product. If there is overload, the RF120C turns off the power supply
to the reader and signals this to the CPU.
