Product Description
Product Overview
The Allen-Bradley 1771-WB is a 12 Point Terminal Field Wiring Arm designed for the PLC-5 system’s 1771 I/O modules, providing a reliable connection point for field wiring in industrial automation applications. Manufactured by Allen-Bradley, a brand under Rockwell Automation known for its durable control solutions, this wiring arm facilitates the termination of field device wires (e.g., sensors, actuators) to compatible I/O modules within a 1771 chassis. It features 12 screw-clamp terminals for secure connections, supporting wire sizes up to 14 AWG, and includes a hinged design for easy attachment and removal without disrupting wiring. The 1771-WB is commonly used with modules like the 1771-ASB (Remote I/O Adapter) and other analog or discrete I/O modules, enhancing flexibility and maintenance efficiency in legacy PLC-5 installations across industries such as manufacturing and process control.
