FAQ
Q: Can the NTDI21-B be used with non-ABB DCS systems?
A: It is optimized for ABB Bailey systems; compatibility with other DCS may require verification.
Q: Does it support high-current digital outputs?
A: Outputs are standard 24 VDC ON/OFF signals; external relays are recommended for high-current loads.
Q: What maintenance is required?
A: Inspect wiring connections and surge protection periodically; module itself is maintenance-free under normal conditions.
Q: Are similar ABB modules available?
A: The NTDI21-A and NTDI22-B provide comparable digital I/O interfaces with variations in channel count and output configuration.
