I/Os
This model comprises a total of 12 inputs 6 relay and 2 npn outputs. Input functionality can be
adapted as follows:
1. 12 inputs may be used as digital inputs. They may be wired in a group via a single jumper
as either npn or pnp.
According to jumper settings and appropriate wiring:
- Inputs 10 and 11 can function as either digital or analog inputs.
- Inputs 0, 2, and 4 can function as high-speed counters, as part of a shaft-encoder,
or as normal digital inputs.
- Inputs 1, 3, and 5 can function as either counter reset, as part of a shaft-encoder,
or as normal digital inputs.
- If inputs 0, 2, 4 are set as high-speed counters (without reset), inputs 1, 3, 5 can function as
normal digital inputs.
Input Jumper Settings
The tables below show how to set a specific jumper to change input functionality. To access the I/O
jumpers, you must open the controller according to the instructions beginning on page 9.
Incompatible jumper settings and wiring connections may seriously damage the controller.
