This module interfaces directly with catalytic bead sensors (mV) or 4–20 mA transmitters to provide continuous atmospheric monitoring in hazardous zones. Featuring a sophisticated four-part liquid crystal display (LCD) and a dedicated alarm reset button, the 05701-A-0302 delivers instantaneous visual feedback on gas concentrations, alarm status, and system health. It eliminates measurement ambiguity by combining a 25-segment analog bar graph with a precise four-character digital readout. This card acts as the intelligence hub for localized gas safety, triggering alarms and protective actions when gas levels exceed user-defined setpoints.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003cth\u003eCategory\u003c\/th\u003e\n\u003cth\u003eSpecification Details\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e05701-A-0302\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSystem Series\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eHoneywell System 57\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDisplay Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFour-Part LCD (Analog Bar Graph + Digital\/Message\/Icons)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput Compatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCatalytic (mV) or 4–20 mA Current Loop\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eResolution\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1% FSD (Full Scale Deflection) steps\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVisual Indicators\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLEDs for A1, A2, A3 Alarms, Fault, and Inhibit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDC Supply\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e18V to 32V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower Consumption\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.75W Typical (Catalytic) \/ 3.25W Typical (4-20mA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAccuracy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e±0.5% FS typical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eElectronic Drift\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; ±2% per 6 months\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e17.0 x 2.5 x 11.2 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.165 kg (Shipping Weight: 1.5 - 2.0 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eEngineering Advantages\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eElimination of Calibration Drift:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThe 05701-A-0302 features a potentiometer-free design.
