Product function
Loop Conditioning: Buffers and linearizes 4–20 mA or ±10 V loops via Bently Nevada 136294-01, applying precise 250 Ω terminations.
Digitization: Converts analog inputs to digital values for transmission over the 3500 backplane bus.
Alarm Logic: Compares each channel against programmable high/low setpoints and flags alarm conditions.
Diagnostics: Detects open-circuit, short-circuit, overrange, and reports faults to the system interface.
Isolation: Provides galvanic isolation to prevent ground loops and protect downstream electronics.
Application Areas
Process Monitoring: Pressure, flow, temperature, and level loops using Bently Nevada 136294-01 in turbines, compressors, pumps, and engines.
Machine Protection: Feeding safety-critical alarms (overpressure, overtemperature) into trip logic.
DCS/SCADA Integration: Converting field loops into digital data with Bently Nevada 136294-01 for plant control systems.
Hazardous-Area Panels: Zone 2/Div 2 installations where internal module isolation replaces external barrier hardware.
Retrofit Projects: Upgrading analog racks using Bently Nevada 136294-01 while retaining existing sensor loops.
