Overview
The Allen-Bradley 1771-WC Series B field wiring swing arm is a PLC-5 accessory designed to provide flexible interconnection between Allen-Bradley 1771 I/O modules and plant wiring. This component features a thermoplastic construction with conformal coating for durability in industrial environments and does not require an external power source.
Key Features
- 8 I/O points with 10 gold-plated terminals for reliable connections
- Conformal coating protects against moisture and contaminants
- TTL low-current module support for digital input/output applications
- No external power required for operation
- AWG 14 wire compatible — supports both spade-lug and direct clamping
- Thermoplastic construction with gold-plated contacts for corrosion resistance
