Control function: Built-in 8 control functions and algorithms Sequence control: Trapezoidal sequence control Logic control: Fuzzy logic control Display screen: 14-segment large color LCD display Language support: English, German, French, Spanish Network interface: Ethernet (Modbus/TCP), RS-485 (Modbus/RTU, Peertopeer, coordinated, PC-Link), open network (PROFIBUS-DP, CC-Link) Power requirements: 24VDC Protection class: Insulation resistance > 5MΩ @ 500VDC (between all input/output and ground) Operating temperature: 0 ° C ~ 55 ° C Storage temperature: -25 ° C ~ 70 ° C Humidity range: Operation: 50% ~ 95%, Storage: 5% ~ 95%。YOKOGAWA UT550-04S4 temperature controller is a leader in the field of industrial automation, which uses advanced control algorithms to provide accurate temperature control. Its large 14-segment color LCD display makes it easy for the operator to read data and view parameters with a scrolling text function. In addition, the controller supports multiple languages, which is convenient for users in different countries and regions to operate.Trapezoidal sequential control and fuzzy logic control make it perform well in complex industrial environments and adapt to various working conditions. Its compact design and depth of only 65mm make it ideal for applications where space is limited. The UT550-04S4 also supports multiple network protocols, such as Ethernet and RS-485, making it easy to integrate into existing industrial control systems. The controller also features high impedance, greater than 5 megohms at 500VDC, ensuring stability and reliability in harsh environments.
