Crowcon Sensitron Multiscan 8+ Gas Control Unit
The Multiscan 8+ is an innovative gas control unit, ideal for small plants with up to 16 or 24 detectors.
Monitor eight gas detectors connected directly to the control panel (4-20 mA) and an additional 12 or 16 detectors via remote 8-input cards STG/IN8S or directly to the serial line. Every input can be configured for a different kind of gas to detect both flammable and toxic compounds, refrigerant gases, and Oxygen depletion or enrichment.
The panel can manage six output relays aboard the panel and an additional 32 or 48 via the additional board STG/16REL or remote modules STG/OUT16S+STG/8REL.
The backlit LCD display accurately indicates the measured gas concentration and alarm set points. Mode status LEDs visually indicate alarm levels, fault and power-on. An internal buzzer is provided for an audible alarm in case of alarm or fault.
