Product Description:

The 134B1730 is a plug-in printed circuit assembly produced by Danfoss for its VLT Control Cards series. Inserted into the option slot of a compatible VLT frequency converter, the card extends drive monitoring and I/O capability so that plant controllers can gather additional status data or issue control commands without external gateways. In HVAC and water-handling installations it forms the interface between the FC-series drive electronics and higher-level automation, maintaining modularity while keeping enclosure space to a minimum.

This option is tailored exclusively to the FC-102 drive platform, ensuring firmware hand-shake and electrical pinout match without field rewiring. A gross shipping mass of 0.18 kg helps logistics planners estimate pallet loads and verify that shock-sensitive hardware is packed correctly. The minimum drive firmware revision is 5.21; using earlier software could block parameter mapping or generate configuration errors during power-up. Classified internally as a Control Card, it plugs onto the main power board and draws its operating power through the host converter, so no auxiliary supply is required. The design omits a built-in Safe Stop function, meaning emergency-stop integrity must be handled by the primary drive or external safety relays.

The card itself weighs 0.12 kg once removed from transit materials, minimizing cantilever load on the drive’s option connector during vibration testing. Its carton occupies just 0.955 cubic decimeter, allowing multiple spares to share limited service-truck storage. Being part of the VLT Control Cards family maintains consistent mechanical keying so technicians can replace modules quickly without adapter brackets. For maintenance staff already standardized on Danfoss architectures, this assembly preserves parameter structure and tool workflow across the installed base.
