I/Os
This model comprises a total of 12 inputs and 6 relay outputs. Input functionality can be adapted as
follows:
1. 8 inputs may be used as digital inputs. They may be wired, in a group, and set to either npn or
pnp via a single jumper. 4 inputs may be used as analog inputs, current (AN2-AN5).
In addition, according to jumper settings and appropriate wiring:
- Inputs 6 and 7 can function as either digital or analog inputs.
- Input 0 can function as a high-speed counter, as part of a shaft-encoder,
or as a normal digital input.
- Input 1 can function as either counter reset, as part of a shaft-encoder,
or as a normal digital input.
- If input 0 is set as a high-speed counter (without reset), input 1 can function
as a normal digital input.
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 10.
Incompatible jumper settings and wiring connections may seriously damage the controller.
Do not move JP2.
