Note
Twisted-pair cables are recommended for I/O signal wiring. The module’s terminal blocks
accept wire sizes between 12 and 22 AWG. A minimum of bare wire should be exposed to
prevent short circuits. Allow some slack when making connections to prevent strain.
2. Insert the exposed end into the clamp beneath the termination screw.
3. Tighten the screw.
Discrete digital outputs
The discrete outputs are located on TB3, which is a 15-pin Phoenix connector, and have
five Form-C relays on the back plane. All contact outputs have a rating of 1A @30 VDC.
