Description
Product Introduction
This GE F31X191RTBAEG2 is an RTD interface board with Ethernet communication for GE’s excitation and power conversion control platforms. The “E” suffix indicates the inclusion of Ethernet connectivity for remote temperature monitoring, and the “G2” suffix indicates a revision 2 design with reliability improvements. This board is designed for applications where temperature data must be accessible from a remote location.
The board interfaces with RTD temperature sensors, providing signal conditioning and temperature measurement. The Ethernet interface allows communication with SCADA systems, remote monitoring software, and plant automation networks. The revision 2 design incorporates improvements for reliability and performance.

Frequently Asked Questions (FAQ)
Q1: What is the purpose of the RTBAEG2 in an excitation system?
A: The board interfaces with RTD sensors for temperature monitoring of generators, transformers, and other equipment.
Q2: What Ethernet protocols does the board support?
A: The board supports Modbus TCP and GE’s proprietary protocols. We can confirm the specific protocol version for the boards in our inventory.
Q3: Can I monitor temperature data remotely?
A: Yes, the Ethernet interface enables remote monitoring of temperature data from a SCADA system or remote workstation.
Q4: Is the Ethernet interface isolated?
A: Yes, the Ethernet interface is transformer-isolated from the board’s logic and measurement circuits.
Q5: What is the lifecycle status of the RTBAEG2?
A: This board is very rare. We have a very small batch of new surplus units. If your system requires Ethernet-enabled RTD monitoring, we strongly recommend securing a spare. We do not expect to source more of this variant.
