Notes:
1. All 10 inputs can be set to pnp (source) or npn (sink) via a single jumper
and appropriate wiring.
2. All 10 inputs can function in 12 VDC or 24 VDC; set via a single
jumper and appropriate wiring.
3. npn (sink) inputs use voltage supplied from the controller’s power supply.
4. Inputs #0, #2 and #4 can each function as either high-speed counter or
as part of a shaft encoder. In each case, high-speed input specifications
apply. When used as a normal digital input, normal input specifications
apply.
5. Inputs #1, #3 and #5 can each function as either counter reset, or as a
normal digital input; in either case, specifications are those of a normal
digital input.
These inputs may also be used as part of a shaft encoder.
In this case, high-speed input specifications apply.

Note:
To avoid electromagnetic interference, mount the controller in a metal
panel/cabinet and earth the power supply. Earth the power supply
signal to the metal using a wire whose length does not exceed 10cm.
Using a wire longer than 10cm will cause signal interference.
