Features:
- Sixteen Independently Programmable Relay Outputs With Failsafe Logic Ensure Reliable Alarm Response
- Epoxy-Sealed Relays With Arc Suppressors Provide Extended Operational Life Up To 10,000 Cycles
- Operates In Harsh Environments With Wide Temperature Range And High Humidity Tolerance
The Bently Nevada 3500/33 149992-02 is a full-height 16-channel failsafe relay module engineered for 3500 series monitoring racks. Each channel can be programmed independently using AND/OR Alarm Drive Logic, responding to alert and danger statuses, Not-OK signals, or measured variables from any monitor channel. Compared to the original 3500/33 relay modules, the 3500/33 149992-02 offers enhanced environmental protection and built-in arc suppression, making it a robust replacement or spare solution for critical monitoring applications.
Designed for industrial reliability, the 3500/33 149992-02 consumes a typical 5.8 watts and includes epoxy-sealed relays with a standard 250 Vrms arc suppressor. Each relay can handle up to 10,000 cycles, providing long-lasting performance. The module’s design allows installation in any slot to the right of a Transient Data Interface (TDI) Module, offering flexible rack configuration.
The module operates from -30°C to +65°C (-22°F to +150°F) and can be stored safely from -40°C to +85°C (-40°F to +185°F). With a humidity tolerance of up to 95% non-condensing, the 3500/33 149992-02 maintains stable performance in harsh, industrial environments. Its combination of programmable outputs, environmental resilience, and reliable failsafe design ensures continuous and accurate monitoring in demanding systems.
The 3500/33 149992-02 Bently Nevada Spare 16-Channel Failsafe Relay Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Condition New Original ready stock
- Product Family 3500/33,3500/33 149992-05,3500/33 149992-06
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Multi-channel configuration: Provides 16 independent relay outputs, which can be flexibly assigned to different alarm groups.
- Fail-safe design: Employs Failsafe logic; when the module loses power or detects an internal fault, the relays automatically switch to alarm mode.
- Logic table driving: Supports complex AND/OR logic settings via the 3500 framework configuration software, responding to various vibration and displacement alarms.
- Status monitoring: Features onboard LED indicators to display the relay engagement/disengagement status and module health of each channel in real time.
- Industrial-grade temperature range: Supports stable operation in ambient temperatures ranging from -30°C to +65°C (-22°F to +149°F).
- Electrical isolation: High-strength electrical isolation between contacts and internal circuitry prevents field-side surges from damaging the monitoring system.
- Shock resistance: Designed to meet nuclear power and heavy industry standards, enabling reliable operation in high-vibration and electromagnetic interference (EMI) environments.
- Physical Coating: Circuit boards typically feature an anti-corrosion coating, adaptable to the salt spray and humid environments of chemical plants or offshore platforms.
- Emergency Stop System (ESD): As the terminal actuator of the 3500 monitoring system, it directly drives the unit's emergency trip circuit.
- Automation Linkage: Transmits vibration alarm signals to the host DCS or PLC system to achieve plant-wide automated logic control.
- Rotating Machinery Protection: Widely used for over-vibration protection of critical assets such as steam turbines, reciprocating compressors, and large fans.
- Spare Part Replacement: This model (-02 suffix) is often used as a field spare part for quickly replacing damaged 16-channel relay packages to restore system redundancy.
