Siemens 39VIMCCN Voltage Input Module Inquiry Item

This Siemens 39VIMCCN is a VIM voltage input module for Siemens APACS+ distributed control system. It is used to collect 0~10V analog voltage signals from field transmitters and sensors. It has 16 independent input channels, with built-in signal filtering and overvoltage protection circuit. After signal conditioning and A/D conversion, the data is transmitted to the DCS controller through the backplane bus. This module has stable acquisition accuracy and strong anti-interference performance. It has been discontinued, widely used as maintenance spare part for old petrochemical, power and refining APACS+ control cabinets.
