Product Overview

The 78462-01 (81545-01) is a specialized signal input and relay card designed for the Bently Nevada 3300 Monitoring System. This module serves as the critical hardware interface between vibration, speed, or position sensors and the plant's protective logic systems. It is engineered to provide reliable relay outputs that trigger automated alarms or emergency shutdowns (ESD) when machinery parameters exceed pre-set safety thresholds. This specific variant is conformal coated, providing a high level of environmental resistance against moisture, dust, and corrosive industrial atmospheres, ensuring the long-term integrity of the machinery protection loop.
