All I/O channels are electrically isolated from the Saia PCD® and the external power supply. (but all channels are electrically connected to each other).Each channel has two connections.6-98PCD3.W525ConfigurationModule connections/LEDsThe module connections are as follows:Description of LED: ● ● ●Off: On: Flashing slowly:Flashing quickly:No power supply to module. Uext (24 V) absent. Module working correctly. Channel error (overload/underload/short circuit/ open load) Uext lower than specified (< 19 V).Configuration of inputsEach input channel is configured via a DIP switch with four pins. The function of each pin is as follows:Pin no. 1 2 3 4Off Differential modeGain=1On Single-ended mode Current shunt resistance on Supply to external resistors on Gain=0,25According to this table, the configuration of the various operating modes is as follows:OnOnOnOffOffOff1 2 3 41 2 3 41 2 3 4sliderVoltage mode 0...10 VCurrent mode 0...20 mA 4...20 mA
