Crowcon Sensitron PL4+D Gas Control Unit
PL4+D, for DIN-rail mounting, is an innovative gas control unit ideal for small plants with up to 12 detectors.
Monitor four gas detectors connected directly to the control panel (4-20mA) and an additional 8 detectors via remote 8-input cards STG/IN8S. 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 5 output relays aboard the panel and an additional 32 via STG/OUT16S+STG/8REL.
The backlit LCD display assures a precise indication of 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.
