Wiring the Redundant Power Inputs
The AWK-4131 must be connected to a power-over-Ethernet (PoE) IEEE
802.3af compliant power source or an IEC60950 compliant limited power
source. When AWK-4131 is powered via DC power, the M12 A-coding
connector on the bottom panel is used for the AWK-4131’s two redundant
inputs. The pin assignment is shown below:
Pin

ATTENTION
This product is intended to be supplied by a Listed Power Unit
marked “Class 2” or “LPS” and rated O/P: 12 to 48 VDC, 890mA
(max.), 25°C.
Make sure external power adapter (includes power cords and
plug assemblies) provided with the unit is certified and suitable
for use in your country.
Before connecting the AWK-4131 to the DC power inputs, make
sure the DC power source voltage is stable.
ATTENTION
Do not use the PoE Injector with the PoE (Power-over-Ethernet)
model. Instead, use an IEEE802.3af or IEEE802.3at compliant
PSE (Power Sourcing Equipment).
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.
