The Dixell XT121D models (DIN rail mounted) are two-state ON/OFF controllers for controlling 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 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 PTC, NTC, Pt100, J, K, S thermocouple signals.
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. The basic version also includes a TTL output for connecting the controller to serial communication. Optionally, the Dixell XT120D controllers can also be supplied with a 4...20mA analogue output or with RS485 communication.
