176F8626 by Danfoss

The 176F8626 is a printed circuit assembly supplied by Danfoss for the Danfoss Cables and Accessories series. Functionally, it serves as a gate-drive interface card that carries firing signals between a VLT power stage and the insulated-gate drivers inside a variable-frequency drive, allowing the inverter section to switch its output devices in a controlled sequence. Integrating this board supports the switching section of an existing drive, so it helps keep installed automation equipment in operation when the original control path for the power stage must be restored.

The board has a coated finish, meaning a conformal layer guards copper traces against conductive dust and moisture inside cabinet environments where airborne contamination can shorten board life. With a net mass of 0.5 kg, the card imposes minimal mechanical load on a drive card cage while remaining substantial enough for stable mounting inside the unit. A carton volume of 7.958 L allows space for antistatic cushioning that helps protect leads and connectors during transport and storage. Electrical compatibility is limited to Danfoss 400 V AC drives marked by voltage codes T4 and T5, and matching those identifiers helps maintain correct bus voltage sensing and gate timing. The assembly is a gate-drive card, so its edge connectors route low-level control pulses while isolating them from the high-energy output stage.

For sites operating 690 V equipment, the same hardware mates only with drives carrying Code T7 that left production before calendar week 08 of 2014, which keeps the board aligned with older back-plane arrangements. Packed accessories raise shipping mass to 0.65 kg, which is useful when several spare units are stored together on shelving or included in larger parts orders. The card is cataloged within the Danfoss Cables and Accessories family, which also includes harnesses, fuses, and other drivetrain auxiliaries used with related drive platforms. This card is intended for use in FC-series drives that require matching gate-drive logic.
