The BENTLY NEVADA 3500/54 133396-01 is a high-reliability overspeed detection I/O module designed for critical rotating machinery protection systems. Part of the 3500 Series by BENTLY Nevada, this module supports redundant configurations (2-out-of-2 or 3-out-of-3 voting) to meet API 670 and API 612 standards for safety-critical applications. It interfaces with proximity probes or magnetic pickups to monitor rotational speed, triggering rapid shutdowns to prevent catastrophic failures in turbines, compressors, and pumps.
