Dixell Digital Thermostat

XH 260L – XH 260V

The XH260L, 38×185 format, and the XH260V, 100×64 format, are microprocessor controllers, suitable for applications on medium or low temperature refrigerating units. They control both humidity and temperature. They have 6 output relays to control compressor, heating elements, defrost, fan dehumidifier and humidifier. They have 2 NTC inputs one for thermostat the other one for defrost. It’s also present and 4÷20mA input for humidity. There is one digital input (free contact) configurable by parameter. An output allows the user to programme the parameter list with the “Hot Key”.

XR 03CX – XR 04CX

The XR03CX, in 32×74x50mm short format, is microprocessor based controller suitable for applications on normal temperature refrigerating units. It provides two relay output: one for compressor and the other one for alarm signalling or as auxiliary output. It provides an NTC probe input and a digital input for alarm signalling, for switching the auxiliary output or for start defrost. The instrument is fully configurable through special parameters that can be easily programmed through the keyboard or the by HOTKEY.

The XR04CX, in 32×74x50mm short format, is microprocessor based controller suitable for applications on normal or low temperature refrigerating units. It provides two relay output: one for compressor and the other one for defrost. It provides two NTC probe inputs, one for room temperature and other one to control defrost termination. The instrument is fully configurable through special parameters that can be easily programmed through the keyboard or the by HOTKEY. 4

XR 20CX

Model XR20C, format 32 x 74 mm, is a digital thermostat with off cycle defrost designed for refrigeration applications at normal temperature. It provides a relay output to drive the compressor. It is also provided with 2 NTC or PTC probe inputs, the first one for temperature control, the second one, optional, to connect to the HOT KEY terminals to signal the condenser temperature alarm or to display a temperature. The digital input can operate as third temperature probe.

The HOT KEY output allows to connect the unit, by means of the external module XJ485-CX, to a network line ModBUS-RTU compatible such as the dIXEL monitoring units of X-WEB family. It allows to program the controller by means the HOT KEY programming keyboard. The instrument is fully configurable through special parameters that can be easily programmed through the keyboard. 3

XR 70CX

Model XR70CX, format 32 x 74 mm, is microprocessor based controller, suitable for applications on medium or low temperature ventilated refrigerating units. It has four relay outputs to control compressor, fan, and defrost, which can be either electrical or reverse cycle (hot gas). The last one can be used as light, for alarm signalling or as auxiliary output. It is also provided with up to four NTC or PTC probe inputs, the first one for temperature control, the second one, to be located onto the evaporator, to control the defrost termination temperature and to managed the fan. The digital input can operate as third temperature probe. The fourth one, to connect to the HOT KEY terminals is used to signal the condenser temperature alarm or to display a temperature..

The HOT KEY output allows to connect the unit, by means of the external module XJ485-CX, to a network line ModBUS-RTU compatible such as the dIXEL monitoring units of X-WEB family. It allows to program the controller by means the HOT KEY programming keyboard. The instrument is fully configurable through special parameters that can be easily programmed through the keyboard. 3

XT-120C, XT-121C, XT-120D, XT-121D

The XT120C, XT121C and XT120D, XT121D (DIN RAIL format) are two-stage ON/OFF controllers for temperature, humidity and pressure applications with direct or inverse action, user-selectable. The analogue input type can be set by parameter between the following, according to the model:

– PTC, NTC;
– PTC, NTC, Pt100, Thermocouple J, K, S;
– 4÷20mA, 0÷1V, 0÷10V.

XT-151 – XT-160D

The XT151D and XT160D (DIN RAIL format) are three (XT151D) or four (XT160D) stage ON/OFF controllers for temperature, humidity and pressure applications with direct or inverse action, userselectable. The analogue input type can be set by parameter between the following, according to the model:

– PTC, NTC;
– PTC, NTC, Pt100, Thermocouple J, K, S;
– 4÷20mA, 0÷1V, 0÷10V.

XW 60L -V_GB

Model XW60L, 38×185 mm format, and model XW60V, 100×64 format, are microprocessor based controllers suitable for applications on medium or low temperature refrigerating units. They are provided with four relay outputs to control compressor, defrost – which can be either electrical or hot gas – the evaporator fans and the lights. They are also provided with 2 NTC or PTC probe inputs, one for temperature control, one to control the defrost end temperature of the evaporator. There are 1 digital inputs (free contact) configurable by parameter. An output allows the user to programme the parameter list with the “Hot Key”.
