Description
The Bently Nevada 3500-32 (125712-01) is a high-reliability 4-channel relay output module designed for the 3500 Machinery Protection System. This module provides essential alarm and trip logic for protecting critical rotating machinery. It interfaces directly with the 3500 rack backplane to receive alarm status from other modules (such as monitors) and enables the activation of external devices, such as machine shutdown switches or emergency alarm systems, based on configured setpoints.
