Description
Product Introduction
This GE F31X306LCCABG1 is a logic and communications controller board for GE’s drive and excitation control platforms. The “LCC” designation identifies this as a Logic and Communications Controller board, providing integrated I/O and serial communication capabilities.
The board provides 24 configurable digital I/O points, dual serial ports (RS-232 and RS-422/485), and a communications co-processor for protocol handling. It is designed for applications requiring both discrete I/O and serial communication in a single board.

Key Selling Points & Differentiators
- 24 Configurable I/O: Each channel can be configured as input or output, providing flexibility for mixed-signal applications.
- Dual Serial Ports: RS-232 for local programming and RS-422/485 for network communication.
- Communications Co-Processor: Offloads serial protocol processing from the main CPU.
- Quantified Testing Protocol: We test all I/O channels under load and verify serial communication at all baud rates.
- Warranty & Support: 2-year functional warranty with application support.
Frequently Asked Questions (FAQ)
Q1: What is the purpose of the LCCABG1 in a control system?
A: The board provides integrated I/O and serial communication, reducing the need for separate modules.
Q2: Does the LCCABG1 support Modbus RTU?
A: Yes, the board supports Modbus RTU over the RS-422/485 port.
Q3: Can all 24 I/O points be used as outputs simultaneously?
A: Yes, all 24 channels can be configured as outputs. Ensure your power supply can handle the total current draw.
Q4: Is the LCCABG1 compatible with other GE boards?
A: Yes, the board is designed for integration with other boards in the series.
Q5: What is the lifecycle status of the LCCABG1?
A: This board is discontinued. We have a limited quantity of new surplus units. If your system requires this board, we recommend securing a spare.
