Sensor Wiring Notes
- For strong interference or inductive loads, it is recommended to use a 220V AC power supply and relay, incorporating a 250V/220nF capacitance for safety regulations.
- The instrument is factory-configured for NPN type sensors. For PNP sensors, customization is required. If using PNP sensors, a suitable value resistor (recommended 510Ω) should be used for indirect IN and COM connections.
