ATTENTION
If the AWK-4252A is connected to a motor or other similar type
of equipment, be sure to use power isolation protection. Before
connecting the AWK-4252A to the DC power inputs, make sure
the DC power source voltage is stable.
Wiring the Digital Inputs and Relay Contact (Digital
Output)
The AWK-4252A has two sets of digital input
—
DI1 and DI2. Each DI
comprises of two contacts of the 8-pin M12 connector on the AWK-
4252A’s
bottom panel. These two digital inputs can be connected to
digital-output-enabled sensors for on-site status monitoring.
The AWK-4252A 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-8PMM-IP68
, is recommended for
connecting the AWK-
4252A’s DIs and relay.

NOTE
Before connecting the AWK-4252A DC power inputs, make sure
the DC power source voltage is stable.
•
The wiring for the input terminal block shall be installed by
a skilled person.
•
Wire type: Cu
•
Only use 16-28 AWG wire size.
•
Use only one conductor in a clamping point between the DC
power source and the power input.
