Product Overview
The Bently Nevada 3500/04-01 136719-01 is a 4-channel relay input/output module designed for the 3500 Series Machinery Protection System. It plugs directly into any 3500 rack and provides four independent Form C (SPDT) relay outputs, allowing vibration, thrust, temperature, or speed monitors to trigger plant equipment or sound alarms. Front-mounted Euro-style pluggable connectors simplify field wiring, reduce commissioning time, and allow hot-swap maintenance without disturbing other modules.

Key Features and Benefits
Four fully isolated relays – each rated at 5 A @ 250 Vac / 30 Vdc, suitable for high-power machine tripping circuits
European-style quick-disconnect terminals – for faster, error-free wiring and easier loop testing
Front-panel LED indicators – provide at-a-glance indication of coil energized/de-energized status
TÜV-certified SIL 2 functionality – compliant with IEC 61508 for safety-critical tripping applications
Plug-and-play integration with all 3500 racks – 3500/22M TDI automatically recognizes the relay, requiring no additional configuration tools
Redundant relay drivers – supports single- or dual-channel voting logic, enabling 2-of-2 or 2-of-3 tripping schemes
Wide operating temperature range – -30°C to +65°C, 5-95% relative humidity (non-condensing), and 3500 series standard shock and vibration resistance

Typical Applications
ESD (Electrostatic Discharge) (ESD) steam, gas, or hydro turbine tripping
Pump or compressor "high vibration" alarm and trip logic
Machine protection for overspeed, differential expansion, or thrust position
Factory-installed DCS/PLC plug-in relays, eliminating the need for external panels
