The Jumo Quantrol is a compact, easy to use, and self-optimizing controller series. The controller is used for two-state and three-state control applications as well as for the control of regulating valves or SCR power controllers via a continuous controller output. The universal analog input is for RTD temperature probes, thermocouples, or current / voltage signals and can be programmed by the user.
