Overview
The 88984-02 Input Relay Option Card is a critical component in Bently Nevada’s legacy 3300 Series and is compatible with the 3500/94M overspeed protection system. It provides two independent output relays with normally open (NO) contacts, enabling seamless connection to external alarm, trip, and control circuits.
Moreover, this module serves as a physical interface between the monitoring rack and field devices, such as speed sensors and shutdown relays. It does not perform signal processing but ensures protection commands are transmitted accurately and reliably. For instance, in a turbine application, the 88984-02 enables fast relay activation during overspeed events, helping prevent mechanical damage.
Its compact form factor and CE certification make it suitable for deployment in industrial environments worldwide, including petrochemical, power generation, and manufacturing sectors.
