GE Fanuc Series 90-30 IC693CBL305 Port Expansion Wye Splitter Cable

Product Overview

The IC693CBL305 is a specialized Wye-style interface cable engineered specifically for the Series 90-30 Programmable Controller line. Its primary function is to expand the physical connectivity of high-density communication modules by splitting a single high-density port into two distinct interfaces. This allows engineers to simultaneously access RS-232 and RS-485 signaling paths, which is critical for complex networking environments involving local HMI connections and long-distance serial daisy-chaining.

Technical Specifications

Module Compatibility and Application

The IC693CBL305 is essential when utilizing Programmable Coprocessor Modules (PCM) or Communications Control Modules (CMM). These modules often utilize a high-density port to save faceplate space. By deploying this Wye cable, the system gains:

• Dual-Protocol Support: Enables the use of CCM, RTU Master/Slave, or SNP protocols across different physical layers.

• Space Optimization: The right-angle connector ensures that the cable does not interfere with the PLC cabinet door, even in shallow rack mounting scenarios.

• Reliable Data Integrity: Built with industrial-grade shielding to maintain signal timing and voltage levels across both the RS-232 and RS-485 branches.

Common Integration Questions

How does the IC693CBL305 handle different voltage levels between RS-232 and RS-485?

The cable acts as a physical pin-out router. The logic separation occurs within the IC693CBL305 wiring harness, directing the specific pins of the module's high-density port to the correct standardized connectors for each protocol, ensuring no signal crossover.

Can this cable be used with the IC693CPU374 or other CPU-based ports?

No, the IC693CBL305 is specifically keyed and wired for the PCM and CMM expansion modules. CPU-integrated ports typically require different pin-out configurations (such as the IC693CBL316 or IC754CBL series).
