Description

HIMA SB3073-EX – Intrinsically Safe Isolator (Thermocouple/RTD Input)

Product Overview

The HIMA SB3073-EX is an intrinsically safe isolator designed for hazardous industrial environments, specifically handling thermocouple, RTD, and millivolt input signals. It acts as a critical interface between field devices and control systems, providing triple isolation between power, input, and output to prevent dangerous energy transfer to explosive zones. This unit solves the problem of signal distortion and safety risks in harsh areas, converting field temperature signals into standard 4-20mA or 1-5V outputs for reliable transmission to DCS/PLC systems, while complying with strict explosion-proof standards.
