Description
Product Description
The IC693CBL302 is a 15‑meter I/O bus expansion cable engineered for the GE Fanuc Series 90‑30 PLC system. Specifically designed as the final link in a daisy‑chain configuration, it connects the CPU baseplate to the last expansion or remote baseplate, ensuring reliable communication across long distances.
Featuring an integrated 100‑ohm termination resistor, the IC693CBL302 eliminates the need for external terminators, maintaining signal integrity at the end of the bus. Its continuous EMI shielding and rugged industrial construction provide high noise immunity and stable data transmission in electrically harsh environments. This makes it ideal for distributed control systems and complex automation setups.
