TPC-X Controller


The TPC-X is a controller designed to operate up to 3 pumps in pump-up or pump-down applications. The controller sequences pumps on and off in response to a change in level input. When used to control the level in a tank, the input is connected to a 4-20mA sensor. A rotary selector wheel is included along with back and escape push buttons for intuitive menu navigation and quick setting adjustments. A 2.7” blue OLED 64 x 256 pixel display provides easy to read level readout and fault annunciation. Download this PDF for more information.
