SFGP series rail-mounted isolation and distribution unit manual, which can provide a isolated power supply for the field-installed two-wire transmitter, and convert the 4~20mA signal from the transmitter into isolated 1~5V/4~20mA signal, achieve the isolation of input, output and power supply.
This document provides an overview of the SFGP series rail‑mounted isolation and distribution devices, explaining their function of isolating power and signal for field‑installed two‑wire transmitters and converting 4‑20 mA signals to isolated 1‑5 V/4‑20 mA outputs.
It includes technical specifications, selection charts, physical dimensions, installation guidance, wiring diagrams, detailed wiring instructions, and calibration procedures for both isolation and distribution units. This manual is written in Chinese.
