Models XW30LH and XW30LRH controllers, dimensions 38x185mm. The controller is suitable for forced air at normal temperature Cold refrigeration unit. 3 relay outputs control the compressor, evaporator fan and lighting respectively. Ability to provide built-in real-time clock (RTC) for cycle defrost control up to 6 times per day, or divided into sections Work on both holidays and working days. "Day and night" function with two different set points, this function It is suitable for energy-saving operation when day and night electricity charges are different. Also provides up to three NTC or PTC sensor inputs The first circuit is used to control the temperature of the storage room, and the second circuit can be placed on the evaporator to control the defrosting termination temperature and the temperature of the fan. Evaporator start and stop temperature. One of the two digital inputs can be defined as the third temperature probe. Fourth temperature probe Can be used to measure condensation temperature (alarm) or to measure and display the temperature at a point. Note: The fourth probe is only suitable for For XW30LH. Parameters can be uploaded or downloaded through the HOT KEY interface of the programming key, through the external communication converter XJ485-CX Converted to ModBUS-RTU protocol, for example, it can be connected to the network of dIXELL's X-WEB series monitoring system. The controller can be programmed via the HOT KEY programming key. The controller provides a full-featured configurable parameter table system that the user can easily access via keyboard buttons programming operation.
