Frequently Asked Questions

Q: What does the 0.190A current draw represent?

A: This is the IOTA's own power consumption from the backplane. Field devices draw separate power from your external 24V supply connected to the IOTA terminals.

Q: How does the redundancy actually work?

A: The CC-TDIL11 splits each field input to two separate input modules. If one module fails, the second continues reading the signal with zero interruption.

Q: Why 4.220 Watts heat dissipation matter?

A: This helps you calculate cabinet cooling needs. The CC-TDIL11 generates 4.22W continuously. Factor this into your panel ventilation design.
