AD-DTR 100 GVF

The differential temperature controller DTR 100 GVF is designed for use in cooling systems for server cabinets or similar systems. With the help of this device system temperatures are regulated and therefore kept stable. The DTR 100 GVF takes two temperatures with the help of his two PT1000 sensor inputs and calculates the temperature difference to regulate the temperature with PI behavior. There are two analog outputs, with which an electric actuator with analog input can be controlled. No external 24V power supply must be set for the supply of this actuator because the DTR 100 GVF has an integrated short-circuit proof power supply for the supply of such an actuator. In addition, the controller includes digital signal inputs and relay outputs. Thus, digital states can be captured or redirected. Alternatively, a digital input can be used for the frequency measurement. Pulse of fans or pumps can be evaluated for speed detection. All analog values and digital states are available via Modbus RTU protocol. Connection of several devices on a bus is possible. This simplifies the monitoring of large installations significantly. For parameterization the DTR 100 GVF includes a front mounted control panel with color LCD screen.
