Control Unit Module Sigma MOD AO

Control Unit Module Sigma MOD AO

Sigma MOD AO is a device designed for collaboration with gas detectors and other associated appliances to make up an overall system Sigma ​Gas developed to provide gas safety on the supervised area. Integration of gas monitoring devices with comprehensive automation and control systems deployed in existing industrial and other facilities is frequently carried out by means of current loops with 4 --20 mA signals. Therefore there is a need to set up an interface between the Sigma ​Gas system that uses digital transmission of information on one side and existing systems of field automation with the current loop 4 – 20 mA to enable easy combining of the both systems. It is the task that is entrusted to the Sigma MOD AO module described in this leaflet.
