Product Infor
|
The Bently Nevada 125704-01 is a high-availability, fault-tolerant relay interface board designed to handle mission-critical industrial machinery emergency shutdown (ESD) actions. Operating under a Triple Modular Redundant architecture, this module houses a physical matrix of twelve independent electro-mechanical relays structured into four separate voting channels. By executing a built-in 2-out-of-3 hardware voting logic mechanism, it ensures that a single-point electronic failure across any individual channel path will neither trigger a nuisance trip nor disable plant safety protection loops. |
|
|
Channel and Relay Density: |
Built with 4 channels, featuring exactly 3 independent relays per channel. |
|
Hardware Voting Structure: |
Implements hardwired 2-out-of-3 (2oO3) voting logic across all output channels. |
|
Maximum Switching Current: |
Supports a continuous current load of 5.0 A per relay point under resistive electrical loading. |
|
System Logic Input Power: |
Powered directly via the 3500 chassis backplane bus at a nominal logic voltage of 24 V DC. |
|
Power Consumption Efficiency: |
Consumes a low maximum footprint of approximately 5.8 Watts under complete multi-channel alarm states. |
|
Environmental Operating Temperature: |
Validated to operate flawlessly within rugged industrial environments from -30 °C to +65 °C (-22 °F to +150 °F). |
|
Storage Temperature Limits: |
Storable inside dry warehouse configurations spanning from -40 °C to +85 °C. |
|
Atmospheric Humidity Tolerance: |
5% to 95% non-condensing relative ambient moisture rating. |
Application
v Emergency Machinery Shutdown (ESD) Systems: Configured as the direct mechanical trip line for high-speed gas/steam turbines and axial compressors within petrochemical refineries.
v Nuisance-Trip Mitigation Control: Deployed inside heavy thermal power generation plants to ensure that an accidental single monitor probe failure never translates into an expensive, accidental factory-wide shutdown.
v High-Risk Industrial Interlocks: Wired directly into localized fuel-shutoff solenoids, hazardous cooling fans, and large lubrication pumps across marine, mining, and oil extraction platforms.
