UNIVERSAL INPUT VOLTAGE 1

Read-only

Voltage measurement value is expressed in mV.

Formula for the current measurements: I=U/200

where: U – register value,

200 – value of attached resistor

Temperature is expressed in Celsius degrees * 10

For a result, divide the registry value by 10.

Selection of the type sensor is done using UNIVERSAL INPUT CONFIGURATION register from 40151 to 40158 for each input separately
