1、Come with three‑proof paint spraying is used to protect circuit boards and related equipment from environmental erosion. Has good resistance to high and low temperature, excellent insulation, moisture resistance, leakage resistance, shock resistance, aging resistance, anti‑corona, etc. 2、DC signal isolator allow 35mm standard rail installation, possess strong versatility 3、Provide input/output/power supply/shell isolation, so that have strong anti‑interference ability and high reliability 4、The product provides isolated power distribution for the transmitter on site, and at the same time isolates and transmits the current signal generated by the transmitter from the site to the control room, PLC, DCS and other input terminal interface current source, two‑wire system, three‑wire system transmitter universal 5、Internal use of good‑efficiency magnetic isolation technology, the input, output, and power supply are isolated from each other, with high accuracy, high linearity, low temperature drift, etc.
