Electric generator HI-301


The HI-300 and HI-301 electric generators are hand-held power generators for panel mounting. They generate a controlled and stable 4 to 20mA loop. By moving the control knob, it is possible to change the value of the output current.

The HI-301 is a manual current generator for panel mounting. It controls a 4 to 20mA loop, powered by the instrument itself.

By acting directly on the knob on the front of the instrument, the output current value can be controlled manually.

The generator has a double indication. The first indication is read on a three-digit numerical display, which shows the output value in percentage mode for the range from 4 to 20mA. The second indication consists of a bar of 10 LEDs that allows to know the output value as an analog approximation.

This electrical generator has a dual power supply system and is powered from a 220Vac mains voltage or from a 24Vdc supply.
