¥999.00

The BENTLY 133396-01 is a core 3500/53 overspeed detection I/O module for Bently Nevada 3500 series machinery protection systems, engineered to prevent catastrophic overspeed in turbines, compressors, and generators, complying with API 670/612 standards. The BENTLY 133396-01 accepts signals from proximity probes/magnetic pickups, processes them via high-speed 24-bit A/D conversion, and supports 2-out-of-2/2-out-of-3 voting for fail-safe protection. It integrates with 3500 racks for redundant power and <10 ms trip response, ensuring rapid action during overspeed events. The BENTLY 133396-01 offers Modbus RTU communication, 4-20 mA analog outputs, and C-type alarm/danger relays, enabling seamless OT-IT integration and real-time monitoring. Its -30°C to +65°C operation and 1000 VAC channel isolation make the BENTLY 133396-01 ideal for harsh industrial settings. It provides 24 VDC (±10%) power with 40 mA sensor excitation, ensuring reliable sensor operation. The BENTLY 133396-01 also features on-board diagnostics for module health checks, reducing unplanned downtime in critical processes like power generation and oil & gas refining.
