Temperature and Humidity Control in Environmental Testing Equipment (Rooms)
Environmental testing equipment (rooms) is key to checking ambient temperature and humidity in environmental worthiness tests for a variety of products (refrigerators, air conditioners, automobiles, etc.), and controllers for such equipment are also widely used.
Temperature and Humidity Control in Environmental Testing Equipment (Rooms)
Advantages of the UT55A
- Equipped with four types of PID value switching (SPNo. switching, PV value zone auto switching, SP value zone auto switching, contact input switching), enabling switching to the optimum PID value in accordance with the test conditions and environment.
- When connecting by wiring to PLC, you can select status switching, one-shot switching, or reverse action for each temperature measurement contact input (DI), which helps reduce the load of the PLC ladder program.
