Bently Nevada 3500/33 Relay Output Module
The Bently Nevada 3500/33 is a multi‑channel relay output module for the 3500 machinery protection system. It receives alarm signals from monitor modules and drives dry‑contact relay outputs to interlock external trip circuits, alarm annunciators and safety‑related auxiliary equipment for rotating machinery protection.
This module supports configurable relay action logic and fault detection functions, providing reliable hard‑wired alarm and trip contact outputs. It serves as essential spare hardware for maintenance and retrofitting of turbine and compressor machinery protection racks.
