Product function
Signal Conditioning: Accepts low-level analog outputs, applies termination and barrier isolation via Bently Nevada 164578-01, then digitizes for rack-bus transmission.
Integrated Barriers & Terminations: Embeds safety barriers and input resistances on-board.
Diagnostics: Monitors loop integrity and reports faults over the digital bus.
Application Areas
Combustible-Gas Detection: Monitoring methane concentrations using Bently Nevada 164578-01 in turbine enclosures.
Toxic-Gas Safety Systems: Integrating H₂S/CO detectors into shutdown logic.
Hazardous-Area Installations: Zone 2/Div 2 control panels with Bently Nevada 164578-01.
Process-Safety Integration: Feeding gas-sensor data to DCS/SCADA systems.
