PoE (Power over Ethernet) device.

Wiring the Digital Inputs and Relay Contact

(Digital Output)

The AWK-4131 has two sets of digital input—DI1 and DI2. Each DI

comprises two contacts of the 8-pin M12 connector on the AWK-4131’s

bottom panel. These two digital inputs can be connected to

digital-output-enabled sensors for on-site status monitoring.

The AWK-4131 also has one relay output, which consists of the two

contacts. These relay contacts are used to detect user-configured events.

The two wires attached to the Relay contacts form an open circuit when a

user-configured event is triggered. If a user-configured event does not

occur, the Relay circuit will be closed.

A field-installable plug, M12A-8PF-IP67, is recommended for

connecting the AWK-4131’s DIs and relay.
