Functional Description
The 1771-W terminal arm is installed directly on compatible 1771-series I/O modules and serves as the primary interface for field wiring. The hinged swing-arm construction enables technicians to remove or replace the module independently from the field wiring assembly, reducing system downtime during maintenance.
Gold-plated terminals improve long-term contact reliability and help maintain signal integrity in industrial environments subject to vibration and electrical noise.
