The General Electric IC693ACC307 is a 25-pin I/O bus terminator plug specifically engineered for the Series 90-30 Programmable Logic Controller (PLC) platform. This essential component is utilized to terminate the I/O expansion bus, ensuring signal integrity and preventing data corruption caused by signal reflections at the end of the communication chain.

Features

• Designed for GE Series 90-30 PLC systems
• 25-pin D-shell connector configuration
• Integrated resistor pack for proper bus termination
• Ensures stable communication between CPU and expansion baseplates
• Supports system configurations up to 15 meters (50 feet) in total cable length

Applications

• Automated sorting and conveyor control systems
• Large-scale industrial material handling
• Food and beverage processing lines
• Robotic assembly and motion control backplane stability

Technical Specifications

Installation Guidelines

• The terminator plug must be installed exclusively on the final baseplate in an I/O expansion chain.
• Locate the "I/O BUS OUT" port on the right side of the last expansion baseplate.
• Insert the IC693ACC307 firmly into the 25-pin connector.
• Secure the connection by tightening the mounting screws on the D-shell connector to prevent vibration-induced signal loss.
• Always power down the PLC system before connecting or disconnecting I/O bus components to prevent electrical damage.
• Failure to install the terminator may result in "Loss of I/O Module" errors or failure of the CPU to recognize remote racks.

FAQ

What is the primary function of the IC693ACC307?

The IC693ACC307 acts as a bus terminator containing a resistor pack. It prevents signal reflections on the I/O expansion bus, which is critical for maintaining reliable communication between the main CPU and remote expansion racks.

Where should this plug be installed?

It must be installed on the "I/O BUS OUT" port of the very last baseplate in your expansion configuration.

Is this component compatible with all Series 90-30 racks?

Yes, it is designed for use with Series 90-30 CPU and expansion baseplates that utilize the 25-pin I/O bus architecture.
