The General Electric IC693CBL305 is a specialized 1-foot Wye (Y) communication cable engineered for the GE Series 90-30 PLC platform. This cable serves as a critical interface component for Communications Coprocessor Modules (PCM) and Communications Modules (CMM), allowing users to split a single high-density physical port into two distinct, manageable serial connections labeled Port 1 and Port 2.

Features

• Designed for seamless integration with Series 90-30 PCM301, PCM311, and CMM311 modules.
• Features a 25-pin right-angle connector for the module-side interface to save space in tight enclosures.
• Splits combined serial signals into two separate, clearly labeled ports for simplified wiring and device connectivity.
• Constructed with 28 AWG wiring to ensure signal integrity for RS-232 and RS-485 communication protocols.
• Provides full compatibility for cables originally designed for Series 90-70 CMM modules when used within a 90-30 environment.

Applications

• Factory automation and assembly line control.
• Process control systems including water treatment and chemical delivery.
• Legacy industrial elevator control systems.
• Food and beverage packaging and bottling line management.
• Robotic pick-and-place and material handling systems.

Technical Specifications

Installation Guidelines

• Ensure the PLC system power is disconnected before installing or removing the cable from the module interface.
• The right-angle 25-pin connector should be seated firmly into the module port; ensure the locking screws are tightened to prevent intermittent signal loss due to vibration.
• Route the cable away from high-voltage AC lines and high-EMI sources to maintain serial signal integrity.
• Ensure the cable is not subjected to sharp bends or excessive tensile stress at the connector junctions.

FAQ

What is the primary function of the IC693CBL305?

The IC693CBL305 is used to physically separate the combined serial port signals from a 90-30 CMM or PCM module into two discrete ports, facilitating easier connection to external RS-232 or RS-485 devices.

Can this cable be used for I/O expansion?

No. The IC693CBL305 is strictly for data communication. It is not compatible with I/O bus expansion; using this cable in an I/O port may result in hardware damage.

What is the difference between this and the IC693CBL316?

The IC693CBL305 is a port-splitting communication cable, whereas the IC693CBL316 is a Station Manager cable designed specifically for the RJ-11 ports found on various 90-30 CPU models.
