3501E/3501T| Triconex |TMR Digital Input Module
Description
The 3501E/3501T is a high-reliability digital input (DI) module designed for safety-critical applications. It features triple-modular redundancy (TMR) to ensure maximum availability and safety. The module has three isolated input channels that independently process all data, ensuring the highest integrity of input signals. Each channel conditions signals independently and provides optical isolation between the field and the Tricon system.
Features
- Triple-Modular Redundancy (TMR): Ensures operation in the presence of single faults.
- Voltage Options: 115 VAC/VDC
- Non-Commoned, Isolated Points: 32 points, enhancing safety and reliability.
- Enhanced Diagnostics: Continuous self-tests and fault detection.
- Hot-Spare Support: Ensures continuous operation during failures.
- Mechanical Keying: Prevents improper installation.
- Diagnostic Indicators: PASS, FAULT, ACTIVE status per point.
