Bently 3500/32 125720-01 4-Channel Relay Module

Engineered for industrial environments where precision and reliability are non-negotiable, the Bently 3500/32 125720-01 4-Channel Relay Module acts as a critical component for machinery protection systems. Its four programmable relay outputs enable tailored alarm logic, making it a go-to solution for managing equipment shutdowns or triggering alerts in response to vibration, temperature, or speed anomalies. Think of it as the unsung hero in a power plant’s turbine monitoring system – quietly ensuring operations stay within safe thresholds.

Industries like oil & gas, power generation, and chemical processing rely on this module to integrate seamlessly with Bently Nevada’s 3500 Series systems. For example, offshore drilling rigs use it alongside 3500/22M modules to automate emergency shutdowns when vibration thresholds are breached. We frequently pair it with 3500/44 communication modules for remote diagnostics or 3500/92 power supply units in high-availability setups. Its modular design allows installation in any available slot within the 3500 rack, right of the 3500/22 TDI module – a boon for retrofitting legacy systems without major architecture overhauls.

What sets this module apart is its balance of ruggedness and smart functionality. The DPDT relays, sealed against dust and moisture, maintain reliability even in environments with extreme temperature swings (-30°C to +65°C operational range). We’ve found the LED indicators (OK, TX/RX, CH ALARM) invaluable for troubleshooting – a technician can spot a communication hiccup or alarm trigger at a glance. The 5A contact rating handles heavy-duty loads like solenoids or contactors, while local alarm logic processing reduces dependency on the host system. For redundancy, it’s common to mirror configurations with a backup 3500/32 module in parallel setups, ensuring zero downtime during critical operations.
