Overview
The Triconex 3301 Digital Input Module (DI3301) processes signals through three independent channels for TMR systems. Moreover, each channel contains an ASIC that continuously scans input points, compiles the data, and sends it to the main processors (MPs). The MPs vote on the received data to ensure integrity, reliability, and fault-tolerant operation.

Functional Highlights
- Fault Detection: The module monitors each channel continuously and activates the Fault indicator if a problem occurs.
- Hot-Spare Capability: Users can replace faulty modules online without disrupting the TMR system operation.
- State Verification: DI3301 validates state transitions and supports Force-to-Value Diagnostic (FVD) for rapid fault detection.
- Mechanical Keying: Prevents improper installation when mounting the module into the baseplate.
- Robust Design: Supports single and multiple fault scenarios, ensuring system reliability even during unexpected failures.
