Functional Features and Connection Capabilities

The ABB Bailey 6637818A1 provides reliable signal transmission between Bailey modules. You can connect a controller module to a remote I/O chassis using this cable. The overall shield protects against electromagnetic interference from nearby power cables. Furthermore, the IDC connectors offer strain relief to prevent wire pull-out.

This cable assembly supports both power and signal in a single bundle. The tinned copper conductors resist corrosion in industrial environments. Additionally, the color-coded wires simplify troubleshooting and replacement. You can bend the cable around corners with a minimum radius of 50 mm.

Installation and Routing Guidelines

First, power down both connected devices before handling this cable assembly. Next, align the 20-pin connectors with their corresponding headers on the modules. Then, press firmly until you feel both connectors click into place. Finally, secure the cable using cable ties at regular intervals along its path.

You must avoid running this cable parallel to high-voltage AC lines. The assembly does not include any ferrite cores for additional noise suppression. Always maintain a minimum separation of 150 mm from power cables. Furthermore, do not exceed the specified bend radius during installation.

This cable assembly works perfectly for connecting ABB Bailey 6637818A1 compatible modules. It suits both new installations and field replacement of damaged cables. You can also use it for temporary test setups during system commissioning. The pre-terminated ends save hours compared to hand-built wiring harnesses.
