WIRING THE DIGITAL INPUT (DI)
The Digital Input accepts one external DC type signal input that consists of two contacts on the terminal block
connector on the switch’s top panel. And can be configured to send alert message through Ethernet when the signal
is changed. The signal may trigger and generated by external power switch, such as door open trigger switch for
control cabinet. The switch’s Digital Input accepts DC signal and can receive Digital High Level input DC 11V~30V and
Digital Low Level input DC 0V~10V.
Here are the steps to wire the Digital Input:
STEP 1
: Insert the negative and positive wires into the
-
/+ terminals, respectively.
STEP 2
: To keep the wires from pulling loose, tighten the wire-clamp screws on the front of the terminal block
connector.
STEP 3
: Insert the terminal block connector prongs into the terminal block receptor, which is located on the switch’s
top panel.
