BENTLY NEVADA 3500/53 133396-01 Overspeed Detection I/O Module

Description

The BENTLY NEVADA 3500/53 133396-01 Overspeed Detection I/O Module is a critical component of the 3500 series machinery monitoring system’s electronic overspeed detection system, designed to monitor overspeed conditions in rotating machinery. It converts sensor signals to digital data for transmission to monitoring systems, and can be coupled to create 2-out-of-2 or 2-out-of-3 voting systems, meeting API Standard 670 and 612 overspeed protection requirements. Key technical specifications include a 24V DC input voltage, typical power consumption of 8.0 watts, and a converter power supply of -24V DC with a maximum 40mA output. The module features epoxy resin sealing for durability, and a recorder output of +4 to +20 mA, proportional to the module’s full-scale rpm range. It accepts single sensor signals from proximity probes or magnetic pickups, with an input voltage range of +10.0 V to -24.0 V; out-of-range signals are internally limited. Operating within -30 degrees Celsius to +65 degrees Celsius, the module weighs 0.45 kg and offers high reliability, fast response, and modular design for easy installation and maintenance. Ideal for use in turbines, compressors, pumps, and other rotating equipment, it provides precise overspeed detection to prevent potential equipment failure.
