Product Features
Bently Nevada 149992-02 has 16 relay outputs that are independently programmable and support AND/OR logic combinations to flexibly match complex alarm conditions.
Bently Nevada 149992-02 has a fail-safe design that complies with ATEX and North American zoning standards to ensure reliability in hazardous environments.
Bently Nevada 149992-02 is subject to safety approvals and relay output voltages typically do not exceed 30 Vrms to avoid the risk of electric shock.
Bently Nevada 149992-02 is used with the 3500 Rack Configuration Software (version ≥ 3.3), Data Acquisition Software (version ≥ 2.40) and Data Display Software (version ≥ 1.40).
Product Using Principle
Bently Nevada 149992-02 receives alarm signals from the 3500 monitor and drives the corresponding relay contacts after judgment by the internal logic processor. Users can configure the trigger conditions of the relays through the software to realize the hierarchical protection strategy.
Input signal: Compatible with alarm status signals (Alert/Danger) from the 3500 monitoring system.
Contact capacity: The typical value is 30 Vdc/2 A (resistive load).
Operating temperature: -30°C to +65°C, suitable for industrial environments.
Power supply: Provided by the 3500 rack power supply (such as 3500/15) with a power consumption of approximately 10.5 W.
Product Application
In centrifugal compressors in refineries, Bently Nevada 149992-02 monitors shaft displacement parameters in real time with 3300 series eddy current sensors. Its 16 relay channels provide graded trigger protection when displacement exceeds the 0.5mm threshold specified in the API 617 standard.
In the thermal expansion monitoring of the turbine casing of the ethylene cracker, Bently Nevada 149992-02 works in conjunction with the 3500/45 displacement monitor to collect expansion data in real time via LVDT sensors. When the axial expansion rate exceeds 0.02mm/min, the relay output drives the hydraulic servo valve to regulate the steam flow, and at the same time triggers the ESD system to start the standby turbine to ensure the continuous operation of the cracker.
In hydrocracking plants with explosive gases, its fail-safe design ensures that the relay contacts remain open in the event of a short-circuit in the sensor line, preventing an explosion caused by an electrical spark. Its 30Vdc/2A contact capacity allows direct actuation of an explosion-proof solenoid valve for emergency shutdown of the fuel supply.
