Version V1 transfer switch input/output board assembly for the Tornatech GPX+GPU — the electric fire pump controller supplied with an integrated power transfer switch. Part number RPP0058. The board connects the transfer-switch section's monitoring and control wiring to the V1 controller's electronics.
First-generation GPX+GPU controllers remain in widespread service, and this V1 board keeps them repairable without replacing the entire controller. If your unit is the later ViziTouch V2 generation, you need the RPP0040 board rather than this one — the two generations are not interchangeable.
Order RPP0058 for Tornatech GPX+GPU version V1 controllers. Cybertronic Controls — veteran-owned and located in Hammond, Louisiana — stocks transfer-switch and I/O boards for both V1 and V2 generations; call 985-351-5681 to match the board to your controller.
