The TCB temperature control board allows the control of most of the company’s electric valves with the use of a generic PID or similar controller, says the manufacturer. With the board, step motors can be modulated in response to an externally generated signal. The board will work with any capacity electric expansion valve, electric suction control valve, or electric discharge gas bypass valve. Pin jumpers permit adjusting board control parameters for a particular application.
