GE DS3800HAFA1E1F Auxiliary Function Card

The GE DS3800HAFA1E1F is a circuit board associated with the GE DS3800 control hardware family. The HAFA board designation is identified in available product references as an auxiliary function card, with another Mark IV parts reference describing the HAFA board as an analog amplifier card. The exact electrical specifications and configuration of the 1E1F version require confirmation against the original board documentation.

Board Construction and Configuration

The board uses a modular rack connector and mechanical retention levers to secure it in its mounting position. Its component layout includes:

• 11 configuration jumpers for circuit configuration.
• 4 trimmer resistors for circuit adjustment.
• 1 x 20-pin connector for cable connections.
• 1 x 34-pin connector for additional board connections.
• Integrated test points for electrical inspection and troubleshooting.

These components provide adjustment and connection points for the board's intended control-circuit functions. Jumper positions and trimmer settings should be checked against the installed board configuration before replacement.

Application and Replacement Considerations

The DS3800HAFA1E1F is listed as a GE Mark IV Speedtronic regulator board. Its exact circuit function should be verified against the original equipment documentation before assigning it to a particular signal-processing or regulation task.

When replacing an existing board, verify the complete part number, connector arrangement, jumper positions, and trimmer settings. Matching the HAFA prefix alone does not establish electrical or functional interchangeability between different revisions.

Frequently Asked Questions

Q: How many configuration jumpers are provided on the DS3800HAFA1E1F?

A: The board has 11 configuration jumpers and 4 trimmer resistors. Their individual settings should be verified against the applicable GE circuit documentation.

Q: Can the DS3800HAFA1E1F replace another DS3800HAFA board?

A: Not automatically. Different HAFA part-number suffixes may represent different board configurations. Verify the complete ordering number and application requirements before substitution.

Q: What should be checked before installing a replacement board?

A: Check the 20-pin and 34-pin connector arrangements, jumper positions, and trimmer settings. Also verify that the replacement matches the original equipment configuration.
