Digital valve controller EKE 400

The EKE 400 controller is a dedicated controller for evaporators typically used in industrial refrigeration applications. EKE 400 will be able to manage the complete operation in cooling and defrost mode. Features • Approved and qualied by Danfoss for refrigeration applications • One product covering multiple valve congurations • HMI includes wizard for easy setup • Multiple EKE 400 can be interconnected for signal sharing via integrated CANBUS. (defrost coordination(1) , temperature sharing etc.) • Easy to connect to third party equipment like PLC via integrated MODBUS • EKE 400 can be connected to AK-SM 800 series • EKE 400 is available without HMI to save cost • One remote HMI can interface multiple EKE 400 • One EKE 400 cover both 24 V AC and 24 V DC • One EKE 400 cover wide voltage and frequency range; 85 – 265 V AC, 50/60 Hz • Flexible Analog input. Cover both Pt-1000/NTC temperature sensor and 4 – 20 mA / 1 – 5 V Pressure transmitter • 2 Digital output out of 8 Digital output is solid state for PWM(2) (puls) valves • EKE 400 with HMI includes multilanguage support (English, Chinese, Portuguese, Spanish) • International units supported. Metric and Imperial • HMI will during setup, lter out irrelevant parameters or conversely, show parameters that are relevant based on earlier selection Application For industrial refrigeration applications the Danfoss EKE 400 can control the operation of the valves and the fans for evaporators to achieve optimal cooling mode and defrost sequence for an effcient, safe and trouble-free operation of the evaporators, complying with IIAR(3) safety recommendations for hot gas defrost.
