Product Overview
The Bently Nevada 3500/34-10-00 125704-01 is a Triple Modular Redundant (TMR) Relay Module engineered for high-integrity machinery protection systems. As part of the 3500 Series, this full-height module provides 4 independent relay outputs (SPDT) with advanced voting logic, ensuring fail-safe operation in critical industrial environments. Designed for seamless integration with Bently Nevada’s vibration monitoring modules (e.g., 3500/42M) and communication gateways (e.g., 3500/92), the 3500/34-10-00 125704-01 delivers real-time actuation of alarms, shutdowns, and process controls while maintaining compliance with API 670 and SIL 3 standards.
Featuring epoxy-sealed construction and galvanic isolation, the module withstands harsh conditions (e.g., EMI, high vibration) and supports 2 A at 30 VDC contact ratings, ideal for low-power applications like solenoid valve control and motor protection. The 3500 Rack Configuration Software enables programmable 2-out-of-3 voting logic, ensuring reliable actuation even if one relay channel fails. Its hot-swappable design minimizes downtime during maintenance, while front-panel LEDs provide instant status updates (green for normal operation, red for alarms).
In automation architectures, the 3500/34-10-00 125704-01 acts as a critical interface between monitoring systems and external actuators. By combining redundancy and diagnostic capabilities, this module enhances operational safety, reduces unplanned outages, and ensures compliance with safety-critical standards in industries such as oil & gas, power generation, and aerospace.

Key Features and Advantages
Triple Modular Redundancy (TMR): The 3500/34-10-00 125704-01 uses three independent relay channels for each output, with 2-out-of-3 voting logic to ensure actuation even if one channel fails. This redundancy is critical for applications where single-point failures could lead to catastrophic consequences, such as offshore platforms or nuclear power plants.
Programmable Logic Flexibility: Supports AND/OR logic for alarm drive functions, allowing relays to trigger based on single or combined inputs from monitoring channels (e.g., vibration, temperature thresholds). Each channel can be configured for normally energized (NE) or normally de-energized (NDE) operation, adapting to diverse control requirements.
Robust Environmental Resilience: Its epoxy-sealed enclosure and arc suppressors (250 VRMS) protect against moisture, dust, and electrical transients. The module’s 10,000-cycle contact life reduces maintenance costs compared to mechanical relays, while galvanic isolation safeguards against ground loops.
Real-Time Diagnostics: Front-panel LEDs provide instant visual feedback on relay status, communication activity, and fault conditions. Built-in self-testing detects open circuits or sensor failures, flagging issues before they escalate. This diagnostic capability simplifies troubleshooting and ensures compliance with safety protocols.
Hot-Swap Capability: The module can be replaced while the system remains powered, minimizing downtime during maintenance. This feature is critical for industries where continuous operation is essential, such as oil refineries and power plants.
Compliance and Compatibility: Designed to API 670 and SIL 3 standards (optional), the 3500/34-10-00 125704-01 integrates seamlessly with Bently Nevada’s System 1 software for advanced analytics. It also supports Modbus RTU via the 3500/92 gateway, enabling data exchange with PLCs and SCADA systems.
Application Areas
The Bently Nevada 3500/34-10-00 125704-01 excels in applications requiring high-reliability relay control for machinery protection:
- Oil & Gas: Triggering low-power alarms and valve actuations in offshore platforms and refineries based on vibration or pressure thresholds.
- Power Generation: Controlling turbine auxiliary systems (e.g., lubrication pumps) and generator synchronization in power plants.
- Aerospace: Simulating fault conditions during engine testing to validate safety protocols.
- Pharmaceuticals: Ensuring sterile environment control in cleanrooms by actuating HVAC systems and airflow sensors.
- Nuclear Energy: Managing reactor coolant pumps and emergency shutdown systems, where redundancy is non-negotiable.
By converting monitoring data into physical actions, the 3500/34-10-00 125704-01 empowers predictive maintenance strategies, reduces repair costs, and ensures compliance with safety regulations. Its adaptability makes it suitable for both standalone systems and large-scale automation networks.
