The GE Fanuc IC693CBL301 is a 6-foot input/output expansion cable, commonly referred to as a Wye cable. Designed for use within the 90-30 series PLC system, this cable features a continuous shield and a 25-pin male connector on one end, with a two-headed connector on the other. The IC693CBL301 facilitates the extension of the input/output bus to the expansion baseplate, serving as a critical solution when standard cables are unavailable in the required lengths. To ensure optimal system performance, it is essential to adhere to specified cable lengths; exceeding these can lead to erratic operation and reliability issues. Users should confirm the compatibility and specifications of all components within the system, noting that a maximum of seven compatible cables can be utilized in the expansion system. The total permitted cable length between the CPU baseplate and the final remote baseplate is 700 feet, while the maximum length for connections from the CPU baseplate to the last expansion plate is 50 feet. The IC693CBL301 cable enhances installation efficiency and reduces the risk of wiring errors, making it a preferable choice over custom solutions. Custom options include point-to-point cables, which have a male connector on one end and a female connector on the other, and Wye cables, which feature a male connector on one end, accompanied by both male and female connectors on the other. Point-to-point cables offer quicker assembly compared to Wye cables, allowing for greater flexibility and efficiency during installation.
