PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-WH is a PLC-5 Field Wiring Arm 16 I/O channels (21 terminals). It provides direct electrical termination for field devices connected to 1771 series input and output modules. The unit features 21 connection terminals to support up to 16 input or output points. It enables field wiring interconnections without disconnecting plant field lines during maintenance.
This assembly includes a conformal coating to protect internal wiring contacts in industrial environments. Terminal screws require a tightening torque of 7 to 9 pound-inches during wiring installation. The hardware operates without requiring external electrical power for its signal routing connections. Physical dimensions measure 4.5 by 12.4 by 6.3 inches for general purpose system deployment.
