Overview
The 3500/34 TMR Relay I/O Module from Bently Nevada is engineered for critical machinery protection applications. Each of its four relay channels receives three independent alarm signals, ensuring accurate and reliable alarm activation through a triple modular redundant (TMR) architecture. Alarm Drive Logic is configurable via the 3500 Rack Configuration Software.
Key Features
- Triple Modular Redundant (TMR) Architecture: Three independent alarm signals per relay channel for maximum reliability
- 2-out-of-3 Voting Mechanism: Ensures dependable alarm activation
- Independent Alarm Contacts: Each relay channel receives input from three separate monitors
- Status Indicators:
- OK LED: Confirms proper module function
- TX/RX LED: Flashes during communication with other modules
- CH ALARM LEDs: Illuminate when a channel enters an alarm state
- Power Consumption: 9.6 W typical
