Description
Product Description
The IC693CBL301 is a 2-meter (6-foot) Wye-type I/O Bus Expansion Cable for GE Fanuc / Emerson Series 90-30 PLCs and PACSystems RX3i platforms. It extends the CPU baseplate’s I/O bus to expansion or remote baseplates, supporting daisy-chain configurations. Its robust Belden 8107 twisted-pair construction combined with continuous foil-and-braid EMI shielding ensures reliable, noise-immune communication even in harsh industrial environments.
The cable features a single 25-pin D-Sub male connector on one end and a dual 25-pin D-Sub connector (male + female) on the other, allowing chaining of multiple expansion racks and proper termination at the last rack. Factory-grade construction reduces wiring errors and simplifies system expansion.
