Detailed Features and Benefits
TMR Architecture for Fail-Safe Operation
The Triconex 2651 utilizes Triple Modular Redundant technology for each output channel. It processes every command through three independent circuits that vote on the final output state. Consequently, a single component failure cannot cause an erroneous output or prevent a required safety action.
115 VAC Switching for Industrial Control
This assembly provides reliable 115 VAC output switching for solenoids, motor starters, and alarms. It handles the voltage levels common in North American industrial installations. Therefore, you can directly interface with existing field devices without additional signal conditioning.
Integrated External Terminator Rack for Easy Wiring
The LB3000107-150 external terminator rack simplifies field wiring connections significantly. It provides clearly labeled termination points that match the output module channels. This design reduces installation time and minimizes wiring errors during system integration.
Comprehensive Online Diagnostics for Critical Integrity
The 2651 assembly performs continuous, automated self-testing during normal plant operation. It immediately detects and reports any internal fault to the main safety processor. This feature ensures you always know the health of your output control paths.
Modular Design for Simplified Maintenance
You can replace the digital output module without disturbing field wiring on the terminator rack. This modular approach reduces downtime during maintenance or troubleshooting activities. As a result, you maintain higher system availability for your safety functions.
