flexotron 2000 EXR 101, 102: Switching units How energy efficiency is improved Switching outputs for the activation of a two-stage fan control. With this you can, for example, retrofit a system with a ventilation control if needed. Areas of application Switching and alarm function in various applications. Features • Easy to operate thanks to analogue user interface • LED display for indication of switching status • Setting options for setpoint and switching difference Technical description • Standard housing as per DIN 43880 made of flame-retardant thermoplastic • Analogue input 0 - 10 V or 4 - 20 mA • 1 potential-free relay contact per switch position • Suitable for mounting on top-hat rail as per EN 60715 • Electrical connection with screw terminals for wires up to 2.5 mm² 1-stage switching unit 2-stage switching unit Setting ranges Setpoint XS1, XS2 Switching difference Power supply 24 V~ Power consumption Permissible ambient temp. Degree of protection frontal Wiring diagram Dimension drawing Fitting instructions Input or Output relay Terminal cover for EXR 101; attains protection class II as per IEC 60730 Terminal cover for EXR 102; attains protection class II as per IEC 60730 Protected against excess voltage up to 20 V– Protected against excess current up to 40 mA Operation The input signal is compared with the setpoint XS1 (XS2) If this is exceeded, contacts 5-4 (8-7) are closed, which is indicated by an LED. If the input signal undercuts the value XS1-XSd1 (XS2-XSd2), contacts 5-3 (8-6) are closed. N.B.: The figures in brackets also apply to EXR 102. Engineering note The contacts are equipped with RC circuitry.
