Parker IQAN-MC31 Instruction Book

19Voltage inputsInstruction book, IQANVoltage inputsConnecting sensors to the voltage inputsThe sensor signal range must be 0-5 Vdc. To detect signal errors such as short circuitsor interruptions the active signal range be within 0.5-4.5 Vdc.Active signal range.The current consumption related to the voltage input is negligible.The positive terminal of the sensor is connected to the +VREF position and thecorresponding negative terminal to the -VREF position. The sensor signal is connectedto appropriate VIN position.N OTICEThe negative terminal of the sensor must not be connected to the chassis.Maximum load for VREF position: see Appendix A.Connecting other 3 wire sensorsThe same type of connection shown for potentiometers is used for other 3 wire sensorssupplied with power from the regulated 5VDC supply, VREF. This includes activetemperature sensor IQAN-ST, pressure sensor IQAN-SP and Hall-effect levers IQAN-LST or IQAN-LSL.EXAMPLEConnect the positive and negative terminals of the position sensor to +VREF,and -VREF, respectively. Then connect the sensor signal to VIN-X.Connecting VREF and sensor signal VIN-X.05[V]Active signal rangeError detection rangeError detection ranget-VREF+VREFVIN-XPosition SensorIQAN module
