Product Description
The Allen-Bradley 1746-C7 ribbon cable, designed for side-by-side connections between controllers and chassis, is 6 inches long and features a thermocouple analog input. It supports backplane currents of 110 mA at 5V and 85 mA at 24V. When connecting SLC 500 controllers, maintain a 2.5 to 4 inch spacing; for 1746-P4 power supplies, the maximum spacing is 2.5 inches. This cable is compatible with Allen-Bradley 1746-A4, 1746-A7, 1746-A10, and 1746-A13 chassis in any combination.
Is Your Device Showing These Signs?
The Allen Bradley 1746-C7 chassis commonly experiences issues such as backplane corrosion leading to communication failures between SLC 500 modules. Power supply degradation causes intermittent system crashes and program corruption. Connector pin damage results in I/O module malfunction and data loss. Resolving these hardware faults through cleaning, power supply replacement, and connector repair restores optimal PLC operation and prevents downtime.
