Knick USA Datasheets for Loop Powered Devices

Loop powered devices are electronic devices that can be connected in a transmitter loop, normally a current loop, without the need to have a separate or independent power source. Typical loop powered devices include sensors, transducers, transmitters, isolators, monitors, PLCs, and many field instruments.
