The Dixell XT121C (in panel) models are two-state ON/OFF controllers for regulating temperature, humidity, pressure, or other variables.
Their two output control relays can be set for two-stage control (e.g. Stage 1 heats a little, Stage 2 heats a lot), but they can also be set for direct or inverted operation without a neutral zone (e.g. Stage 1 output for heating, Stage 2 output for cooling). The third output relay is an alarm relay and allows reporting or handling of alarm conditions. Their analog input can be set to signals of 4÷20mA, 0÷1V, 0÷10V type.
All XT series controllers are equipped with a digital input, optional buzzer and can be programmed quickly and easily using the HOT KEY programming key. In the basic version there is also a TTL output for connecting the controller to serial communication.
