Bently Nevada 125720-02 SIL 2 Compliant Hazardous Area Certified 4-Channel Relay Output Module
For a process expansion, we got DCS-compatible sensors from Amikon, no changes needed, no downtime.
On a packaging line update, their advice on sensor position and controller choice made the line run smoother, fewer errors.
During an emergency shutdown, they shipped parts overnight and guided the install, helped avoid production loss.
They also found old PLC modules that were no longer available, so we could keep the old lines running without redesign.

Key Features
  • SIL 2 & Hazardous Area Certified Compliance
    Engineered specifically for hazardous area deployment and functional safety systems. Fully certified to support SIL 2 compliant safety system architectures, guaranteeing reliable operation in explosive and high-risk industrial environments.
  • Advanced 4-Channel AND/OR Voting Logic
    Features 4 independent relay channels that support programmable AND/OR voting logic control. Allows precise customization of emergency trip and alarm triggers based on multi-channel inputs from the 3500 rack.
  • Fail-Safe Machinery Emergency Shutdown (ESD)
    Acts as the critical hardware link for machinery emergency shutdown (ESD) and emergency trip systems (ETS). Instantly executes over-speed trips and emergency stops to provide ultimate critical asset protection for rotating machinery.
  • Flexible SPDT Contact Configuration
    Equipped with standard Single-Pole, Double-Throw (SPDT contact switching) layouts. Offers both Normally Open (NO) and Normally Closed (NC) dry contacts to easily integrate into diverse industrial automation interlock and alarm status relay output loops.
  • Seamless 3500 System & TDI Integration
    Designed exclusively for the Bently Nevada 3500 rack, providing 100% plug-and-play TDI module integration. Fully configurable via standard 3500/01 configuration software as high-reliability 3500/32 relay system spares.

Application Areas
  • Emergency Shutdown Systems (ESD) & Emergency Trip Systems (ETS)
    Serves as the primary hardware execution interface for machinery emergency shutdown (ESD). It relays critical trip commands to instantly isolate or shut down high-risk machinery during catastrophic failure events.
  • SIL 2 Compliant Safety Interlock Loop Integration
    Deployed in high-integrity automation loops that require certified SIL 2 compliant safety system architectures. It manages the alarm status relay output and fail-safe voting actions to prevent operational common-mode failures.
  • Hazardous Environment Automation Control
    Optimized for hazardous area safety interface tasks within Class I, Division 2 / Zone 2 environments. It safely bridges the gap between digital monitoring chassis logic and field-located physical actuators without risks of ignition.
  • Critical Rotating Asset Protection for Turbomachinery
    Protects vital heavy-industry assets including steam turbine monitoring networks, gas turbine protection setups, and massive centrifugal compressor monitors. It monitors severe fault indicators like over-speed or high radial vibration to initiate defensive trips.
  • Oil & Gas and Power Plant Instrumentation Loops
    Used in refineries, petrochemical plants, offshore platforms. API 670 interlocking for protection loops, equipment and personnel safety.

Frequently Asked Questions
Q1: What is the function of the Bently Nevada 125720-02 module in a 3500 system?
A: 4-channel relay output module in 3500/32M. Takes alarm from rack, turns into relay outputs for shutdown / trip / alarm via AND/OR logic. Mainly machinery protection use.
Q2: What is the difference between 125720-02 and 125720-01?
A: 125720-01 for normal industrial. 125720-02 for hazardous / safety systems. 30 Vac / 30 Vdc limit, usually SIL 2 related applications, oil & gas side.
Q3: Where is the 125720-02 usually applied?
A: Turbines, compressors, rotating equipment. Refineries, power plants. Protection loop, triggers shutdown when vibration / thrust out of range.
Q4: What are the relay specs of the 125720-02?
A: 4 SPDT channels, NO/NC contacts. 2A max, 30 Vdc / 30 Vac. 100 mA minimum load @ 12 Vdc.
Q5: How is the 125720-02 installed in a 3500 rack?
A: Rear I/O behind 3500/32M. Config in 3500/01 software. Works with TDI and rack processor, integration is straightforward.
