Allen-Bradley 1771-WB Field Wiring Arms

Allen-Bradley 1771-WB Field Wiring Arms

Description

The Allen-Bradley 1771-WB is a dedicated field wiring arm for Rockwell Automation's PLC-5 series, engineered for reliable interconnection between 1771 series I/O modules and plant field wiring. It serves as critical connection hardware within industrial automation control systems. Its core purpose is to simplify wiring operations and ensure stable signal transmission, offering broad compatibility with analog I/O applications. It operates independently without requiring an external power source.

This product is specifically designed for Allen-Bradley 1771 series I/O racks (A or B series), particularly suited for wiring connections with the 1771-QA stepper motor positioning module. It serves as an ideal accessory for analog signal transmission in PLC-5 systems. Operating temperatures range from -40°C to 85°C, with storage temperatures spanning -40°C to 85°C, ensuring reliability in demanding industrial environments. Compliant with authoritative standards including UL, it seamlessly integrates with Rockwell Automation's industrial control ecosystem, delivering stable connectivity for automation systems in automotive manufacturing, process control, equipment monitoring, and related fields.

Features 

• Reliable Connection Configuration: Features 12 gold-plated terminals. The gold plating enhances electrical conductivity and corrosion resistance, supporting up to 8 I/O points. Compatible with direct clamping of 14-gauge wire or spade connectors. Standard wiring torque is 7-9 lb-in, ensuring a secure, non-loosening connection.
• Industrial-Grade Durability: Constructed from high-strength thermoplastic material with a triple-protection coating, it withstands industrial environment hazards like dust and moisture. The locking latch design further reinforces connection integrity, preventing vibration-induced contact failure.
• User-Friendly Operation: Features an integrated swing-out mechanism and universal I/O rack clamp, enabling “lift-off” access for simplified module servicing and wiring maintenance. Quickly access modules without disassembling the entire wiring assembly.
