Wiring Digital Signals: Control Panel Build Series Part 18

Wiring: Digital Signals

Can be different depending on the hardware that is being used
Some PLC’s have prewired harnesses that are provided
In which case you will only have to wire the terminal block side of the signal
Sometimes you must wire both the PLC and the terminal block side

Wire size can vary depending on signal types.
Typically use between 16awg to 24awg

Read PLC hardware manual to get a clear understanding of how the circuits should be wired
This can very greatly depending on manufacturer
Land power correctly and Neutral or DC- correctly to ensure a proper loop

It is a good idea to have some kind of disconnect or fused protection on each signal so that you can isolate that signal if necessary
In this case we have used fused protection

Make sure to take time as each termination is made to not fray or “birdcage the wire in anyway

If Jumpers are being used to distribute power, make sure that each terminal the jumper is being inserted into is secured if necessary

Reference the drawings often through the process to ensure that nothing is missed, and each signal is being wired correctly.
