Overview

4-20mA (0-20mA) current loop isolator IC. ISO 4-20mA is a single-chip two-wire isolation interface IC chip used for signal interference isolation and suppression between analog channels in industrial fields, and for 4-20mA current loop isolation, acquisition, and distribution between sensors and PLCs, DCS, and frequency converters.

Product Details

SIP12 Pin packaged current loop isolation chip:4-20mA (0-20mA) current loop isolator ICIt is a single-chip two-wire isolation interface IC chip used for signal interference isolation and suppression between analog channels in industrial fields, as well as 4-20mA current loop isolation, acquisition and distribution between sensors and PLCs, DCS, and frequency converters.4-20mA (0-20mA) current loop isolator ICInternally, it includes modulation and demodulation circuits, coupling isolation conversion circuits, etc. The very small input equivalent resistance enables the input voltage of the IC to reach a wide range (8.5~28VDC), allowing users to achieve long-distance and distortion free signal transmission without the need for an external power supply. The internal ceramic substrate, printed resistor process, and new technology isolation measures enable the device to achieve an insulation voltage of 3KVDC and meet the requirements of harsh environments such as wide temperature, humidity, and vibration in industrial sites.
