I/Os
SM35/43/70-J-R20 comprises a total of 12 inputs and 8 relays.
Input functionality can be adapted as follows:
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 5 and 6 can function as either digital or analog inputs.
If the digital inputs function as npn, analog option is not available.
- 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 a counter reset, normal digital input, or as part of a shaft-encoder.
- If input 0 is set as a high-speed counter (without reset), input 1 can function
as a normal digital input.
SM35/43/70-J-T20 comprises a total of 12 inputs and 8 transistor outputs.
Input functionality can be adapted as follows:
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.
- Outputs 0 to 6 can be used as PWM outputs.
Input and Output 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 on page 11.
Incompatible jumper settings and wiring connections may seriously damage the controller.
