  • Power Status: Always power down the I/O chassis before inserting or removing the module to prevent electrical damage.
  • Keying: Install plastic keying bands between pins 10 and 12, and between pins 16 and 18, to ensure correct slot alignment.
  • Mounting: Align the module with the chassis card guides and apply firm, even pressure until the module is fully seated in the backplane. Secure the module using the integrated chassis latch.
  • Wiring: Utilize the 1771-WH wiring arm for signal termination. Ensure screw terminals are tightened to 7-9 inch-pounds.

FAQs

What is the 1771-IBD?

The 1771-IBD is a 16-channel discrete DC input module designed to interface field-level binary signals with Allen-Bradley PLC-5 systems.

Can I replace the module without rewiring?

Yes, the included 1771-WH wiring arm allows you to remove the module from the chassis while leaving the field wiring connected to the arm, significantly reducing downtime during maintenance.

What are the keying requirements for this module?

To prevent incorrect module insertion, keying bands must be placed between pins 10-12 and 16-18 on the backplane connector.
