Wiring Options for the I/O Module
Included with your 32-point I/O module is a keyed 40-pin female connector and crimp type
pins. These components allow you to wire I/O devices to the module using a 40-conductor
cable or individual wires. Refer to page 13 for connector/pin assembly instructions. When
assembled, align the female connector over the modules male header using the keying slot as
a guide. Firmly lock them together with the upper and lower retaining arms. 1492 pre-wired
cables and interface modules can be used for connecting external I/O.
There are two options for wiring the 32-point I/O module.
Option 1 - Wiring the 1746-N3 Connector
(1) Maximum user cable length is dependent on how much voltage drop (current x (ohms/ft.) x (feet)) the user’s system can
tolerate. The user’s system should take into account the minimum turn-on voltage required by external loads connected to
the 32-point output module, the minimum turn-on voltage required by the 32-point input module, and all of the voltage
drops associated with wiring to and from the load, sensors, terminal blocks, power sources and the module itself.
