The C-mac signal converters are used to convert various kinds of non-standard electrical input signals to standard engineering units (0-20 mA, 4-20 mA or 0-10 V signals).
The input signals can be AC or DC current and voltage (up to 10 A and 1500 V), temperature sensors, proximity sensors for speed monitoring, resistors and potentiometers, 1- and 3-phase load and power monitoring, etc.
Most of the units gives a galvanic isolation between suppy, inputs and outputs, thereby ensuring a safe isolation between the process control equipment and the external environment.

The converters are divided in 3 main groups:
