To connect to a PNP-compatible PLC input, connect Output 0, Output
1, Output 2 or Output 3 directly to the PLC input. When enabled, the
output pulls the PLC input up to greater than 21V.

High Speed Out 0
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 +24V. When the output switches on, the negative side of the load
is pulled down to less than 3V, and 24 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 +24V.

To connect to an NPN-compatible PLC input, connect Output 0, Output 1,
Output 2, or Output 3 directly to the PLC input. When enabled, the output pulls
the PLC input down to less than 3V.

High Speed Output Wiring
For PNP lines, the external load should be connected between the output and
the negative supply voltage (0V). When connected to a 24VDC power supply,
the outputs pull up greater than 21V when ON, and current flows through the
load. When the outputs are OFF, no current flows through the load.
