PLC-5 I/O Connection and Hardware Interface Characteristics
The 1771-WD provides a mechanical and electrical termination interface between field wiring and compatible 1771 digital I/O modules. The pivoting design allows the wiring arm to swing upward for module insertion or removal while maintaining connected field conductors.
The component supports PLC-5 I/O density scaling by allowing multiple field wiring configurations across 1771 chassis modules. Tin-plated contacts provide the electrical interface between terminal connections and the installed I/O module.
The wiring arm requires no external power source and functions as a passive connection accessory. Its conformal coating supports installation in industrial control cabinets where protection of exposed circuit surfaces is required.
Frequently Asked Questions
Q: Does the 1771-WD require an external power supply?
A: No. The 1771-WD is a passive wiring accessory and does not require external power.
Q: How many field terminals are available on the 1771-WD?
A: The wiring arm provides 12 terminal connections.
Q: Can the 1771-WD be removed with field wiring connected?
A: The pivoting design allows the connected wiring arm to move with the module interface, reducing the need to disconnect field conductors during module service operations.
Field Installation Guidelines
Install the 1771-WD by attaching it to the pivot bar at the bottom of a compatible 1771 I/O chassis. Verify that the wiring arm is correctly aligned with the installed I/O module before tightening terminal connections.
Route field wiring according to standard industrial cabinet practices and maintain separation between low-level signal conductors and high-current power wiring. Ensure terminal screws are tightened using the specified torque range.
Inspect contact surfaces and terminal connections during installation. Confirm that the wiring arm is fully seated before placing the I/O module into operational service.
