Sensors
The following sensor types can be connected to the analog inputs of the RTU:
• passive sensors, that get power supply from the RTU, and
• active sensors that have their own power supply.
The sensors should deliver 4–20 mA current. Voltage drop is 8V.
General instruction
Follow these steps to connect analog inputs.
