Description

The BENTLY 136719-01​is a 4-channel relay output module designed for Bently Nevada’s 3500 machinery protection system.This critical safety component provides reliable shutdown and alarm functions for rotating equipment protection applications.As part of the 3500 series framework,it ensures safe system operation by executing protective actions based on monitoring module commands.

Application Scenarios

In a natural gas compressor station,multiple BENTLY 136719-01​modules were deployed to provide emergency shutdown functions for three centrifugal compressor trains.During a sudden surge event detected by vibration monitors,the 136719-01​module immediately de-energized its relays,triggering the compressor’s anti-surge valves and initiating a safe shutdown sequence.This rapid response prevented potential compressor damage estimated at over$2 million,while maintaining pipeline integrity.The module’s redundant design ensured continuous protection even during the shutdown sequence,with automatic fault detection alerting operators to the event.

Technical Principles and Innovative Values

The BENTLY 136719-01​employs high-reliability electromechanical relays with gold-plated contacts for minimal contact resistance and long service life.Each channel provides completely isolated Form C contacts(SPDT)that can be configured for either alarm or shutdown functions.The module’s innovative design includes continuous self-monitoring of relay status and coil health,providing early warning of potential failures before they compromise system safety.

A key innovation in the BENTLY 136719-01​is its dual-watchdog circuit that continuously monitors the module’s microprocessor and power supply.If any abnormality is detected,the module can be configured to drive the relays to their de-energized(safe)state.This fail-safe design ensures that system safety is maintained even in the event of module failure.The relays are magnetically shielded to prevent interference between channels in high-density installations.

Application Cases and Industry Value

In a combined-cycle power plant,the BENTLY 136719-01​modules provided critical turbine protection during a lightning strike that caused a control system disturbance.While other non-essential systems faltered,the 136719-01​modules maintained their protective functions,initiating a controlled shutdown of the gas turbine when vibration levels exceeded safe limits.The plant’s maintenance director noted:”The 136719-01​modules performed exactly as designed during an extreme event,preventing what could have been a catastrophic turbine failure.”

The reliability of the BENTLY 136719-01​was further demonstrated in a petrochemical complex where the modules have accumulated over 15 years of service without a single failure in safety functions.This track record has led to the specification of 136719-01​modules for all critical machinery protection applications across the facility’s expansion projects.

Related Product Combination Solutions

The BENTLY 136719-01​integrates seamlessly with various 3500 series modules including the 3500/42M​vibration monitors,3500/32​axial position monitors,and 3500/25​temperature monitors.For system integration,it pairs with the 3500/92​communication gateway and 3500/95​display.In redundant configurations,multiple 136719-01​modules can be used with voting logic for high-availability applications.The module also interfaces with 3500/15​TMR interfaces for triple modular redundant systems.

Installation,Maintenance,and Full-Cycle Support

Installation of the BENTLY 136719-01​requires proper seating in the 3500 series rack with secure backplane connection.Each relay output should be wired using appropriate gauge wires based on the load current,with proper strain relief to prevent terminal damage.The module’s LED indicators provide immediate status feedback,while the built-in diagnostics can be accessed through the 3500 configuration software.

Routine maintenance includes annual verification of relay contact resistance and operational timing.The hot-swappable design allows for module replacement without system shutdown,though proper safety procedures must be followed.Our technical support team provides comprehensive documentation and 24/7 support for critical applications.
