The Intelligent MIC control unit (IMCU) EC-912-25 gives you the possibility to remotely control your MIC Smoke Measuring Equipment Type EC-912 through a standard RJ45 Ethernet or USB network connection.
The IMCU is a plug-in replacement for the original MCU Controller EC-912-20. It provides the same external interfaces and offers remote control of calibration and operation using an Ethernet or USB connection.
The system is completely controllable through a XML-RPC protocol or partly by a Web interface both over a network connection.
The IMCU offers network control of the following MIC-functions
Command to adjust the chamber voltage (Uc) Command to automatically calibrate the MIC system Command to read the chamber voltage (Ux)
For general information regarding the complete MIC system, please contact us for the “Instruction manual for Smoke measuring equipment MIC type EC-912” (B-281-0006-XX).
For information regarding the XML-RPC interface, please contact us for the document “IMCU EC-912-25 XML-RPC protocol description” (B-281-0007-xx).
Technical specifications
The MIC smoke measuring system type EC-912 consists of the following parts:
MIC smoke measuring head
Multi-cable, 10 m (other lengths on request)
MIC control unit with power supply
Flow control unit with filter
