Description
Product Introduction
This GE F31X139APMASG2 is a custom application-specific advanced protection module for GE’s excitation and power conversion control platforms. The “S” suffix indicates a special application variant with custom firmware or configuration for specific protection requirements. This board is designed for specialized applications where standard protection functions are insufficient or where unique protection algorithms are required.
The board provides protection functions tailored to the specific application, with custom firmware loaded for the particular requirements. The revision 2 suffix indicates this is an updated version with design improvements. This board is typically found in OEM-specific systems or specialized power generation applications.

Frequently Asked Questions (FAQ)
Q1: What is the difference between the APMASG2 and the standard APMABG2?
A: The APMABG2 is the standard protection board with standard firmware. The APMASG2 contains custom application-specific firmware for specialized protection requirements. The hardware is similar, but the functionality differs.
Q2: What applications use the APMASG2?
A: This board is typically found in OEM-specific systems or specialized power generation applications requiring unique protection algorithms. The specific application depends on the firmware loaded.
Q3: Can the APMASG2 be reprogrammed for a different application?
A: The firmware is typically not field-reprogrammable. The board is configured for its specific application at the factory. We recommend verifying the firmware version for your specific application.
Q4: Can the APMASG2 replace a standard APM board?
A: Only if the standard application matches the custom firmware functions. The board will not provide standard protection functions if the firmware is application-specific. Verify compatibility before installation.
Q5: How do I verify the firmware version on the APMASG2?
A: The firmware version is typically indicated on a label on the EPROM or can be read through the system interface. We can verify the firmware version for the specific boards in our inventory.
Q6: What is the lifecycle status of the APMASG2?
A: This board is extremely rare. GE produced the APMASG2 in very limited quantities for specific OEM applications. We have a very small batch of new surplus units. If your system requires this specific board, we strongly recommend securing a spare. We do not expect to source more of this variant.
