Dixell XR50CX 5N0C1 cooling controller with active defrost - replacement for XR60CX

These Dixell XR50CX models are functionally quite comparable to the popular XR60CX models. They are particularly suitable for medium or low temperature cooling applications. They are designed for panel mounting and have dimensions of 32 × 74 mm. They are equipped with three relay outputs:

1. for compressor control
2. for defrost (can be either electric or reverse cycle - hot steam)
3. for controlling the fan, lighting or for alarm reporting

Dixell XR50CX are equipped with up to four inputs for PTC or NTC temperature sensors. One for temperature control, the second located on the evaporator (used for defrost termination temperature control and fan control), the third and fourth are optional (connected to the HOT KEY connector and to the dig.input) for signaling a condensing temperature alarm or just to display any temperature on the remote display. The units also have a digital input for alarm signalling, for switching on the auxiliary output or for defrost triggering. The digital input can optionally be configured for a fourth temperature sensor.

The HOT KEY output can be used to connect the instrument (using the external XJ485-CX module) to a Dixell XWEB monitoring system. The instruments can be fully configured with parameters that can be easily programmed using the keypad or HOT KEY programming key. The compressor output relay has a load rating of 20A (8A inductive load). The other two relays are rated at 8A (3A inductive load) and 5A (2A inductive load).
