User’s Manual of IGSW-24040T
2.2.5 Wiring the Digital Input / Output
The 6-contact terminal block connector on the rear panel of IGSW-24040T is used for Digital Input and Digital Output. Please
follow the steps below to insert wire.
1. IGSW-24040T offers two DI and DO groups. 1 and 2 are DI groups, 3 and 4 are DO groups and 5 is GND (ground).The 6
pin is useless.

3. There are two Digital Input groups for you to monitor two different devices. As following topology shows how to wire DI0
and DI1.
The accecpting voltage of 2 digital input groups is -30V DC maximum, current is 8mA maximum.
The accepting voltage of 2 digital output groups is -30V DC maximum, current is 200mA maximum.
