Model XW90L, with an external dimension of 38x185mm, is suitable for microcomputer controllers for medium or low temperature forced air cooling systems. It has 6 relay outputs to control compressor, evaporator fan, defrost (defrost can be electric defrost or hot gas defrost) light Lights and one alarm and one custom output. It is able to provide a built-in real time clock RTC can be used for up to 6 ¡El second defrosting cycle can also be divided into two situations: holidays and working days. A "day and night" has two ¡El functions of different setting values ​​can be suitable for energy-saving operation at different time of day and night. Two-way NTC or PTC transmission Sensor input (the first and second temperature probes), the first is used to control the temperature of the room, and the second can be placed in the evaporator It is used to control the defrost termination temperature and the evaporator start and stop temperature of the fan. ¡El 1st channel with the highest number of 2 channels can be defined as the first channel Three-way temperature probe (specify when ordering). A fourth temperature probe can be used to measure condensation temperature (alarm) or are used to measure and display the temperature of a point. . Hot key HOT KEY output allows to connect to the device, convert to ModBUS-RTU through external communication converter XJ485-CX protocol, can be connected to the X-WEB series monitoring system network of dIXEL monitoring system. Hotkeys can also be used HOT KEY Use the keyboard to program the controller program. ¡El controller provides a fully functional configurable parameter table setting that can be easily programmed by the user via keypad buttons operate.
