IC693CBL304 GE Series 90-30 PCM300 Splitter Cable 1ft

Product Overview

The GE Fanuc IC693CBL304 is a specialized, highly compact 1-foot (0.3-meter) port expansion "Wye" cable engineered exclusively for the Series 90-30 Programmable Coprocessor Module (IC693PCM300). This ultra-lightweight adapter, weighing only 0.14 kg (0.31 lbs), serves as a signal splitter, separating combined RS-232 and RS-485 communications from a single physical port on the PCM host module into two distinct, isolated connections. Equipped with a space-saving right-angle male connector on the module side and dual-female connectors on the output end, it delivers seamless signal routing without adding physical strain or bulky weight to your PLC rack assembly.

Key Advantages

• Dual-Protocol Separation: Effortlessly splits combined lines to deliver dedicated RS-232 signals on one leg and RS-485 signals on the other, allowing simultaneous dual-port operation.
• Right-Angle & Compact Design: The module-end connector features a right-angle profile, and at a minimal weight of just 0.14 kg, it fits neatly into tight control panels and shallow enclosures without straining delicate ports.
• Continuous Shielding: Encased in high-quality, continuous electrical shielding to block electromagnetic interference (EMI) and preserve communication speeds in noisy industrial environments.
• 90/70 to 90/30 Compatibility: Standardizes physical connections, making the Series 90/70 PCM interface fully compatible with Series 90/30 PCM module hardware.

Quick Installation & Safety Tips

• Equal Potential Grounding: Ensure that the IC693CBL304 cable shielding, the host PCM module, and the PLC baseplate are all tied to the same electrical ground potential. Caution: Ground loops or mismatched voltage potentials can permanently damage connected programming terminals or internal module electronics.
• Align Right-Angle Connector Carefully: When plugging the right-angle male end into the PCM module, line up the pins smoothly before applying pressure to avoid bending the pins in the module's communication port.
• Port Identification: The dual-female end splits the signals into Port 1 and Port 2. Refer to your system program configuration to ensure the RS-232 serial link and RS-485 serial link are mapped and connected to the correct corresponding output ports.

Technical FAQs

Q1: Why does this cable split into two connections from a single physical port?

A1: The IC693PCM300 module consolidates both RS-232 and RS-485 pinouts into a single high-density connector to save space. The IC693CBL304 Wye cable acts as a hardware splitter, separating these signal lines into two independent physical ports (Port 1 and Port 2) to allow simultaneous connections.

Q2: What happens if the cable and baseplate are not grounded at the same potential?

A2: Failure to ground the system at equal ground potential will lead to stray currents flowing through the communications line. This can cause communication faults, signal corruption, or catastrophic hardware damage to the PCM module, the cable, and connected programmer devices.

Q3: Is the IC693CBL304 cable included when I buy the IC693PCM300 module?

A3: Yes, this Wye cable was originally supplied standard inside the box with the IC693PCM300 module. However, because it can wear out or get lost during field servicing, it is also available as an individual replacement accessory.
