Operational Precautions | Best Practices
-
Hot Swapping: Supports module replacement during operation. Ensure the new module version matches the existing system configuration.
-
Wiring Integrity: Use shielded and grounded 24V DC wiring to prevent signal interference.
-
Firmware Sync: Verify that the module firmware is compatible with the TriStation 1131 software settings.
-
Handling: Always use an ESD wrist strap when touching the module to prevent damage to internal components.
Common Q&A | Technical Support
Q: What is the TMR feature for this module? A: Triple Modular Redundant (TMR) means the module uses three independent circuits to vote on signals, preventing a single hardware failure from stopping the system.
Q: Can the DI2301 detect cable faults? A: Yes, it includes diagnostic functions to identify open or short circuits based on the system setup.
Q: Does it require external power? A: Yes, the digital inputs need an external 24V DC power source to operate the loops.
