Input/output (I/O) modulesPCD2.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).6Configuration of inputsEach input channel is configured via a DIP switch with four pins. The function of each pin is as follows:Pin no.
