Dixell XR30CX 5N1C1 cooling controller with defrost, auxiliary relay and buzzer

The Dixell XR30CX models are microprocessor-based passive defrost thermostats suitable for normal temperature cooling applications. They are designed for panel mounting and have dimensions of 32 × 74 mm. They are equipped with two relay outputs. One for compressor control and the other for light, alarm or auxiliary output. Up to three PTC or NTC temperature sensors can be connected. One for temperature control, the second and the third are optional (connected to the HOT KEY connector and to the dig.input) to signal a condensing temperature alarm or just to display any temperature on a remote display. The Dixell XR30CX units also have a digital input for alarm signaling, to turn on the auxiliary output or to trigger defrost. The digital input can be optionally configured for a temperature sensor. The HOT KEY output can be used to connect the unit (using the external XJ485-CX module) to a Dixell XWEB monitoring system. Communication is via ModBUS-RTU protocol. The instruments can be fully configured with parameters that can be easily programmed using the keypad or the HOT KEY programming key. This model is equipped with a compressor relay with a load rating up to 20A (8A inductive load). The auxiliary relay has an ampacity of 8A (3A inductive load).
