Designed for:
01. Power supply of gas alarms ДАТ-М, alarms СТМ-30-10 – СТМ-30-16, gas analyzers ДАХ-М, ДАК, ДАМ, potentiometric analyzers of ion activity АП430-02 (hereafter – detectors);
02. Measurement of output current signals of detectors on each channel;
03. Generation of light and sound alarm when values exceed/drop below the set threshold values along with simultaneous switching of “dry” relay contacts.
Application:
Detection of pre-explosive concentrations of flammable gases and vapors, monitoring of hazardous substances and oxygen content in the air of indoor working area and outdoor facilities of explosion- and fire-hazardous plants and facilities of chemical, petrochemical and petroleum refinery industries.
Units are fixed automatic devices.
