Wiring Procedure
Use crimp terminals for wiring; use 3.31 mm ² –0.13 mm² wire (12-16 AWG):
1. Strip the wire to a length of 7±0.5mm (0.270–0.300“).
2. Unscrew the terminal to its widest position before inserting a wire.
3. Insert the wire completely into the terminal to ensure a proper connection.
4. Tighten enough to keep the wire from pulling free.
Input or output cables should not be run through the same multi-core cable or share the same wire.
Allow for voltage drop and noise interference with I/O lines used over an extended distance.
Use wire that is properly sized for the load.
The controller and I/O signals must be connected to the same 0V signal.
I/Os
SM43-J-R20/SM35-J-R20
comprises a total of 12 inputs and 8 relays.
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 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.
SM43-J-T20/SM35-J-T20
comprises a total of 12 inputs and 8 transistor 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.
