Allen-Bradley 1771-WD FIELD WIRING SWING ARM

Allen-Bradley 1771-WD FIELD WIRING SWING ARM

Description

The Allen-Bradley 1771-WD is an industrial-grade field wiring arm designed by Rockwell Automation specifically for the PLC-5 series. Its core purpose is to provide stable and reliable circuit interconnection for the 1771 series digital I/O modules. Operating independently without an external power source, it serves as critical supporting hardware for connecting modules to field circuits within industrial automation control systems. Featuring convenient installation design and industrial-grade durability, it seamlessly adapts to diverse digital signal transmission scenarios, making it the ideal wiring solution for factory automation and equipment control projects.

This product is specifically designed for Allen-Bradley PLC-5 series controllers and 1771 series digital I/O modules, with compatibility for digital input/output modules such as 1771-ID, 1771-OD, and 1771-OZL. Operating temperature range spans 0°C to 60°C, with storage temperatures tolerating -40°C to 85°C. Humidity resistance extends from 5% to 95% non-condensing, fully meeting the demands of diverse harsh industrial environments. Compliant with international safety standards including UL, CE, and CSA, the product seamlessly integrates with the Rockwell Automation PLC-5 system ecosystem. It delivers stable signal transmission support for both new project deployments and legacy system maintenance, reducing wiring failure risks and maintenance costs.

Features 

• Precision Fit and Reliable Connection: Equipped with 12 tin-plated terminals supporting 8 I/O points, compatible with 0.75mm² to 1.5mm² wire gauges. Standard wiring torque of 7-9 lb-in ensures secure, non-loosening connections, effectively reducing signal transmission loss.
• Industrial-Grade Durability: Constructed from high-quality brass alloy with an epoxy resin coating and covered with a conformal coating, it resists dust, moisture, and other industrial environment interferences, offering excellent environmental adaptability and corrosion resistance.
• Convenient Installation and Maintenance: Mounted via a pivot rod at the bottom of the I/O chassis, the module rotates upward for connection. Its “hot-swappable” design allows rapid module installation or removal without disconnecting system wiring, significantly improving maintenance efficiency. Locking tabs on the module secure the wiring arm in place, preventing poor contact caused by vibration.
