SWING / WIRING ARM TERMINAL BLOCK
Wiring arms provide an easy, flexible interconnection between plant wiring and Allen-Bradley 1771 I/O modules. The integral I/O chassis clamp provides swing-away operation for easy module access; an integral module locking tab helps ensure connection integrity. Constructed of an industrial-grade thermoplastic, each wiring arm has one (two for isolated circuits) connection point for each required input or output to the module, plus any needed ancillary connection points for line or signal input power and ground or return. Incoming wires (14 AWG max) may be directly clamped or spade-lugged to the arm. Wiring-arm contacts to the I/O module are either tin or gold plated.
The 1771 Fused Wiring Arm (1771-WHF, -WHFB) provides fuse protection for each output of a module and eases fuse replacement without removing a module from the chassis.
The loss of a single circuit will not affect any other signals in the 16-output module
Replace fuses by removing individual fuse holders without removing the output module
Completely compatible with the 1771-WH Wiring Arm and can be used as a direct replacement
