FAQ

Q1: Does the DDO02 support mixed-voltage output configurations?
It operates within a 24–48 V DC range, although all connected loads should match the system’s defined voltage.

Q2: Can the module be replaced without shutting down the entire rack?
Hot-swap capability depends on the specific SD Series base system, so procedures may vary by installation.

Q3: How is the module configured in ABB engineering tools?
Engineers use FC 221 for module settings and FC 225 for per-channel parameters.

Q4: Are protective features active on every channel?
Yes, each output includes short-circuit detection and overcurrent protection for enhanced reliability.

Q5: Is this refurbished version supported by ABB?
Refurbished DDO02 units function identically to standard models, though support depends on site maintenance agreements.
