Compact 32-point Solid-state 24V dc Source Output Module 9 Mount Module to Panel Mount the module to a panel using two screws per module. Use M4 or #8 panhead screws. Mounting screws are required on every module. Mount Module to Panel Using the Dimensional Template Host Controller Spacing for Single-wide Modules 35 mm (1.378 in.) Spacing for One-and-a half-wide Modules 52.5 mm (2.067 in.) Refer to Host Controller Documentation for This Dimension. Overall hole spacing tolerance: ±0.4 mm (0.016 in.).
Compact 32-point Solid-state 24V dc Source Output Module 6. Attach the modules to the panel using the mounting screws. TIP If mounting more modules, mount only the last one of this group and put the others aside. This reduces the remounting time during drilling and tapping of the next group. 7. Repeat steps 1 to 6 for any remaining modules. Mount Module to DIN Rail The module can be mounted using these DIN rails. • 35 x 7.5 mm (EN 50 022 - 35 x 7.

Compact 32-point Solid-state 24V dc Source Output Module Ground the 1769-OB32T Module This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Additional grounding connections from the module’s mounting tabs or DIN rail (if used) are not required unless the mounting surface cannot be grounded. Refer to Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley publication 1770-4.1, for additional information.
Compact 32-point Solid-state 24V dc Source Output Module 15 The 1492 interface module stick-on labels are abbreviated as follows: +V1 = V dc 1, +V2 = V dc 2, CM1 = Com 1, and so on. 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.

Compact 32-point Solid-state 24V dc Source Output Module Transistor Output Transient Pulses The maximum duration of the transient pulse occurs when minimum load is connected to the output. However, for most applications, the energy of the transient pulse is not sufficient to energize the load. A transient pulse occurs in transistor outputs when the external dc supply voltage is applied to the output common terminals (for example, via the master-control relay).
