. Product Name
3500/32 125712-01 is a Bently Nevada 3500 Series 4-Channel Relay Output Module (also referred to as Bently Nevada 3500/32 Alarm & Trip Relay Module, Industrial Machinery Protection System Relay Card), a core safety and alarm output component designed for Bently Nevada 3500 Machinery Protection System (MPS).
2. Product Description
The 3500/32 125712-01 module is an industrial-grade relay output module developed by Bently Nevada (a Baker Hughes company, part of GE Vernova) for the 3500 Series Machinery Protection System. As a critical interface between the 3500 monitoring system and field safety devices, its primary function is to receive alarm/trip signals from 3500 system monitors (e.g., vibration, temperature, speed monitors) and output relay contacts to trigger protective actions—such as emergency shutdown (ESD), equipment tripping, or audible/visual alarms.
Featuring 4 independent, configurable relay channels, the module supports flexible alarm/trip logic customization to meet specific machinery protection requirements. It adopts a rugged industrial design with enhanced electromagnetic interference (EMI) resistance and wide environmental adaptability, ensuring reliable operation in harsh industrial environments (e.g., power plants, refineries, turbomachinery installations) with temperature fluctuations, vibration, and electrical noise.
Seamlessly integrating with the 3500 Series system chassis and monitoring modules, the 3500/32 125712-01 complies with global industrial safety standards, providing fail-safe operation to protect critical rotating machinery (turbines, compressors, motors, generators) from damage due to abnormal operating conditions. It is widely used in power generation, oil and gas, petrochemical, and manufacturing industries.
