Typical Field Wiring And Internal Module Wiring - DirectLOGIC DL405 Manual

Typical Field Shown below is a wiring diagram with typical field wiring and details relating to the
Wiring and Internal D4–INT module's internal wiring. There are a few things you need to know before
Module Wiring you connect the field wiring.

These points show you how to
connect the interrupts with a single
supply. This method can only be
used if no channel-to-channel
isolation is required .
Each channel is isolated, so you can use sinking or sourcing
configurations independently for each point.
Unused inputs do not require any connections.

* Response delay switch is set with Switch 2,
positions 5–8 on rear of the module. This is only
for points X0 – X3. Points X4 – X7 are fixed at the
fastest response.
