Product Description
Product Overview
The Allen-Bradley 1771-WN is a Field Wiring Arm with 32 terminals, designed for use with PLC-5 1771 I/O modules in industrial automation systems. Manufactured by Allen-Bradley, a brand under Rockwell Automation known for its dependable control solutions, this wiring arm provides a robust connection point for field wiring, such as sensors and actuators, to high-density digital I/O modules like the 1771-IBN (32-point input) and 1771-OBN (32-point output). It features 40 pins with 32 active screw-clamp terminals, supporting wire sizes up to 14 AWG, and includes a hinged, swing-away design for easy installation and removal without disturbing connected wires. The 1771-WN is optimized for modules requiring extensive I/O points, making it suitable for legacy PLC-5 systems in industries such as manufacturing and process control. As part of the discontinued 1771 series, it remains critical for maintaining existing installations.
