High Speed Output Wiring

To connect to an NPN-compatible PLC input, connect one of the high-speed outputs of the reader directly to the PLC input. When enabled, the output pulls the PLC input down to less than 3 V DC.

To connect to a PNP-compatible PLC input, connect one of the high-speed outputs of the reader directly to the PLC input. When enabled, the output pulls the PLC input up to greater than 21 V DC.

To connect the high-speed outputs to a relay, LED or similar load, connect the negative side of the load to the output and the positive side to +24 V DC. When the output switches on, the negative side of the load is pulled down to less than 3 V DC, and 21 V DC appears across the load. Use a protection diode for a large inductive load, with the anode connected to the output and the cathode connected to +24 V DC.
