Install the Module

What This Chapter Contains

Read this chapter for information about how to install the modules.

The 1734-VHSC module is a two-module set. Module 1 houses the

1734-VHSC functionality while module 2 provides screw terminals

necessary to access chassis ground (Chas Gnd) and common (C).

Module 2 also connects terminal 4 to 5 and terminal 6 to 7 for ease of

wiring power to the input device. Module 2 is not necessary for VHSC

functionality but eases customer wiring. Module 2 does not use a

node address, and it doesn’t consume power from the POINTBus. To

reduce loop area, place module 2 adjacent (either side) to module 1.
