Product Features And Image
Internal Fuses: Each group of 8 outputs is internally fused (four 4.0A, 250V normal blow fuses), providing protection for individual groups and preventing a fault in one group from affecting others. Electrical-Optical Isolation: Provides isolation between the field wiring and the PLC backplane, enhancing system protection and noise immunity. Conformal Coating: Often comes with a conformal coating for enhanced protection against environmental factors. PLC-5 Family: Designed specifically for the Allen-Bradley PLC-5 series of controllers. 1771 I/O Chassis: Mounts into a 1771 I/O chassis (e.g., 1771-A1B through -A4B or later models). Wiring Arm: Uses the 1771-WH or 1771-WN field wiring arm for convenient connections, allowing the module to be removed without disconnecting wiring. Addressing Compatibility: Compatible with 1-slot addressing with restrictions, or 1/2-slot addressing with no restrictions. Not compatible with 2-slot addressing. |  |
