Discretes transducer can measure all electrical quantities, both AC and DC, such as current, voltage, power, frequency, resistance and so on. The transducers are mounted on DIN-rail type DIN EN 50022 35. The larger case sizes also have screw fixing.
The transducer converts the input signal into a proportional DC signal that is independent of load and electrically isolated. AC power is measured using a principle based on the TDM (time-division multiplexing) system. An analog DC signal can also be converted into a proportional pulse output, for example to indicate energy consumption.
