76 / 182 page  63 When an inductive load is connected to an I/O Unit, connect a surge suppressor or diode in parallel with the load, as shown in the following diagram. The diode will adsorb the back electromagnetic field generated by the load. L IN COM Diode DC input OUT COM Relay Output Unit Triac Output Unit OUT COM Relay Output Unit Transistor Output Unit Diode L L + Surge suppressor where for the surge suppressor, Resistor: 50 W Capacitor: 0.47 F Voltage: 200 V and the diode, Breakdown voltage: at least 3 times load voltage Mean rectification current: 1 A Input Units Voltage Inputs Do not wire voltage inputs as shown on the left below. + 0 V Sensor power supply Voltage output Output COM (–) IN DC input Incorrect + 0 V Sensor power supply Voltage output Output COM (+) IN DC input Correct Input Leakage Current When two-wire sensors, such as photoelectric sensors, proximity sensors or limit switches with indicators are connected to the PC as input devices, the input bit may be turned ON erroneously by leakage current. In order to prevent this, connect a bleeder resistor across the input to reduce the input impedance.
