Wiring Diagram

Illustration

The following figure shows the 140 DAO 842 20 wiring diagram.

1.

N / C = Not Connected

2.

This module is not polarity sensitive.

3.

When field wiring the I/O module, the maximum wire size that should be used is 1-14 AWG or 2-16 AWG; the minimum size is 20 AWG.

NOTE: The tightening torque must be between 0.5 Nm and 0.8 Nm.

NOTICE

DESTRUCTION OF ADAPTER

Before tightening the locknut to the torque 0.50...0.80 Nm, be sure to properly position the right-angle F adapter connector.
During tightening, be sure to maintain the connector securely.
Do not tighten the right-angle F adapter beyond the specified torque.

Failure to follow these instructions can result in equipment damage.

CAUTION

DAMAGE TO MODULE OUTPUTS

Ensure that the AC power energizing each group is from a common, single-phase AC power source.
Protect the module output when an external switch is used to control an inductive load in parallel with the module output. Use an external varistor (Harris V390ZA05 or equivalent) in parallel with the switch.

Failure to follow these instructions can result in injury or equipment damage.

NOTE:

The output protection is composed of an RC filter (snubber filter) and a varistor:

The snubber filter is optional. The values of R and C are not provided as they depend on the device used.
Choose the varistor with appropriate electronic characteristics depending on the voltage required by the device used.
