Each channel has one input terminal (V
in
) for voltage input. All
eight voltage inputs share a common ground reference, the COM
terminals. If you are using an external supply to power field
devices, connect the power supply to the V and C terminals of the
terminal base or connector block. Field devices source power from
the V
sup
and COM terminals. Refer to the following section for
detailed wiring diagrams.
Caution
Cascading power between two modules defeats
isolation between those modules. Cascading power from
the network module defeats all isolation between
modules in the FieldPoint system.
