Allen-Bradley 1771-WC Wiring Arm

Allen-Bradley 1771-WC Wiring Arm

Description

The Allen-Bradley 1771-WC is an industrial-grade field wiring terminal designed by Rockwell Automation specifically for the PLC-5 series. Its core purpose is to provide stable and reliable line interconnections for TTL low-current I/O modules, serving as critical supporting hardware for connecting modules to field wiring in industrial automation control systems. Operating independently without an external power source, its streamlined design and industrial-grade durability make it an ideal wiring solution for factory automation, equipment control, and similar applications.

This product is specifically designed for Allen-Bradley PLC-5 series controllers and TTL low-current I/O modules, finding extensive application in industrial scenarios such as automotive manufacturing, process control, and equipment monitoring. Its operating temperature range spans -40°C to 85°C, with storage temperatures also covering -40°C to 85°C. Humidity tolerance ranges from 5% to 95% non-condensing, fully meeting the demands of various harsh industrial environments. Meeting industrial-grade quality standards, the product seamlessly integrates with the Rockwell Automation PLC-5 system ecosystem. Whether deployed in new projects or used for legacy system maintenance, it delivers stable signal transmission support while reducing wiring failure risks and maintenance costs.

Features 

• High-Reliability Connections: Features 10 gold-plated terminals for enhanced conductivity and corrosion resistance, supporting 8 I/O points. Compatible with 14-22 AWG wires, enabling direct clamping or spade terminal connections. Standard wiring torque of 7-9 lb-in ensures secure, non-loosening connections.
• Industrial-Grade Durability: Constructed from high-strength thermoplastic material with a triple-protection coating, it withstands industrial environment hazards like dust and moisture while delivering outstanding EMI/EMC immunity, making it suitable for complex and harsh field conditions.
• Convenient Installation and Maintenance: Features a swing-away “flip-off” design with removable terminal blocks, enabling rapid module servicing without disassembling the entire wiring harness. Its compact 1-slot width perfectly fits the 1771 Series I/O rack, ensuring strong installation compatibility.
