Product Description
Product Overview
The Allen-Bradley 1771-WF is a Field Wiring Arm with 18 gold-plated 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 reliable control solutions, this wiring arm provides a secure and flexible connection point for field wiring, such as sensors and actuators, to isolated analog input and output modules like the 1771-IL and 1771-OFE. It features 18 screw-clamp terminals with gold plating for enhanced conductivity and corrosion resistance, supporting up to 8 I/O connection points. The 1771-WF’s hinged, swing-away design allows for easy installation and removal without disturbing connected wires, making it ideal for maintenance in legacy PLC-5 systems used in industries such as manufacturing and process control. Discontinued as part of the broader 1771 series, it remains critical for supporting existing installations.
