Aim Dynamics offers a range of options for applications that require current transducers and voltage transducers with a 4 to 20 mA output:
AC Amp Input -> 4-20 mA Output. This line of current transformer with 4 20mA output produce a 20 mA signal at the rated current and 4 mA at zero. The split-core current sensors are passive but some of the 4-20 mA Rogowski coil kits require external power.
AC Volt Input -> 4-20 mA Output. These small-sized 4 20mA current transducer devices convert the 333mV output of a CT into a 4-20mA signal.
DC Amp Input -> 4-20 mA Output. This line of DC current transducer 4 20mA devices provide a 20 mA signal at the rated DC current, and a 4 mA when there is no signal. Unlike most other current sensors, these sensors require a constant power source to provide the 4-20 mA signal.
DC Volt Input -> 4-20 mA Output. These current transducers convert a DC Voltage, up to 1000 Vdc, to a corresponding 4-20 mA signal.
