PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-WB is a PLC-5 field wiring arm designed for analog I/O modules. This unit provides direct connection points between external field devices and the 1771 I/O chassis. It features twelve terminal positions that support up to eight analog I/O channels. The gold-plated contacts maintain secure electrical transmission across industrial environments.
The assembly uses a thermoplastic housing equipped with conformal coating for component protection. It operates as a passive interface and does not require an external power supply. Field technicians can terminate wiring directly using clamps or spade lugs. Terminal screws support a recommended installation torque range of 7 to 9 lb-in.
