1.Description:
XY-WT04 is a K-type digital high temperature controller module. It can be widely used at smart home, Industrial control, Automatic irrigation, Indoor ventilation.

XY-WT04 high temperature control module has high precision output automatic constant temperature panel. XY-WT04 adopts industrial-grade chip with high-precision K-type thermocouple temperature sensor that can measuring -99℃~999℃ or -99℉~999℉.

2.Features:
【2 Control Methods】: Modbus-RTU control by programmable code and command which can be embedded into industrial control systems to achieve intelligent control; Buttons control is the simplest and most direct which allowing anyone to operate it directly.

【Heating/Cooling Mode】: Automatically control load’s working status by the current temperature and set values. It can control heating equipment and refrigeration equipment according to actual needs. Symbol ‘ H ’ and ‘ C ’ can indicates current working mode.

【K-type Thermocouple】: Waterproof metal probe sensor measuring temperature rang is -99℃~999℃ or -99℉~999℉, Unit switchable, Temperature can be calibrated, high/low temperature alarm, forced start delay avoid frequent starts in a short period of time.

【10A Relay Switch Output】: 10A controllable load, controlled voltage can reach up to DC30V or AC250V as required. Symbol ‘ OUT ’ can indicates current output status. Emergency stop can protect the normal operation of the load and module.

【HD LCD Display Screen】: Direct and clear display. Multiple parameters can be displayed simultaneously. Current temperature, Set temperature, Work mode, Temperature unit, Output status. Backlight can be closed to enter power-saving state.
