Product details
1、 Product Overview
The SNDE-AI/U series AC current/voltage transmitter is used to isolate and convert AC signals from AC transformers into standard process current/voltage signals for control rooms, PLCs, DCS, and display instruments.
The internal adopts efficient magneto electric isolation technology, which isolates the input and output from each other and has strong anti-interference ability. It has the characteristics of high precision, high linearity, and extremely low temperature drift.
Choose between two installation methods: DIN rail and flat screw fixation.
