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 or Output 1
directly to the PLC input. When enabled, the output pulls the PLC input down to
less than 3V.
