The GE IC693CBL313 is a purpose‑built I/O bus expansion cable for GE Series 90‑30 PLC systems. It belongs to the family of “Wye” I/O expansion cables used to extend I/O bus wiring between the CPU baseplate and expansion or remote baseplates. This cable is a key accessory when your automation design requires extended distances between baseplates or additional I/O slots without adding extra CPUs or complex wiring.
