MicroLogix 1762-IQ32T DC Input Module
13
Publication 1762-IN019B-EN-P - June 2013
Wiring Options for the I/O Module
Included with your 32-point input 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 Assemble the Wire Contacts on page 15 for more information on
connector/pin assembly instructions.
When assembled, align the female connector over the module’s male header using the keying slot
as a guide. Firmly lock them together with the upper and lower retaining arms.
Wire the 1746-N3 Connector
TIP
If you decide to build your cable using another 1746-N3 to terminate the cable at the
1492 Interface Module end, wire it in the following manner: Pin 1 to Pin 1, Pin 2 to
Pin 2, Pin 3 to Pin 3, and so on.
ATTENTION
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 connector, power sources and the module itself.
