Notes:
1. The total number of inputs is 22. All of these may be used as normal digital
inputs. Via jumper settings and wiring, certain of these inputs may be
adapted to analog inputs.
2. All 22 inputs can be set to pnp (source) or npn (sink) via a single jumper
and appropriate wiring.
3. npn (sink) inputs use voltage supplied from the controllers 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.
6. 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.
If your conditions do not permit this, do not earth the power supply.
