Product Description
The Allen-Bradley 1771-WD is a removable field wiring arm designed for selected 1771-series digital and analog I/O modules in the PLC-5 / 1771 I/O platform. It provides a secure and organized interface for field wiring, allowing sensors, actuators, switches, and other devices to connect directly to the I/O module without disturbing module electronics.
