Product Description
The 81034-01 is a 6-channel analog conditioning and logic board for the Bently Nevada 3300 Series Machinery Protection System. Serving as the primary processing engine for the 3300/30 (Thermocouple) and 3300/35 (RTD) modules, this board provides high-precision temperature monitoring for critical rotating machinery, including motor bearings, pump casings, and gearbox sumps. Integrated with the 3300 rack backplane, it triggers Alert and Danger relay outputs, enabling automated machinery trips and safety interlocks. Its built-in noise filtration ensures reliable operation in high-EMI industrial environments.
