Replacement input/output board for the Tornatech GPD diesel fire pump controller, version V1. Part number RPP0057, supplied as a complete board assembly. On a V1 GPD, this board carries the controller's field input and output connections for the diesel engine installation.

The V1 designation matters: this board fits first-generation GPD controllers only. GPD controllers built with ViziTouch V2 use the RPP0009 diesel I/O board instead, and a second-generation V1 board (RPP0060) also exists — check your controller's version plate or the markings on your original board before ordering.

RPP0057 is in stock at Cybertronic Controls, a veteran-owned supplier of fire pump controller replacement parts in Hammond, Louisiana. Side-view and top-view photos of the board are on this page for visual matching — call 985-351-5681 if you would like help identifying your board.
