Precautions
3 PROPER APPLICATION
Each node can consist of either a G72C Remote Terminal or a
G71 Remote Interface and G7TC I/O Block pair.
Each Remote I/O Subsystem connected to a Master Module can
contain up to 32 nodes.
Never connect or disconnect a G71 Remote Interface without first
turning off the power. Failure to turn off the power can result in
operational errors.
Be sure to supply the correct power to each Remote Module and
combine only compatible units.
I/O specifications are provided in the following. Proper
combinations can be checked with label colors.
The G71 Remote Output Interface corresponds to NPN
(-- common). Use the NPN-output G7TC Models (+ common)
when connecting.
Always confirm that all G71 and G72C Units have been turned on
before turning providing power to the Master.
All Remote Modules are available as 24 VDC Input or 24 VDC
Output models.

Connections
Correct Example
Incorrect Example 1
Incorrect Example 2
Always wire in order from the Master,
connecting positive to positive and negative to negative, without branching.
The wiring below is incorrect
because positive has been
connected to negative.
The wiring below is incorrect because
a branch has been created.
