ABB DO910 S900 Digital Output Module

FAQ (Frequently Asked Questions)

Q1: What is the maximum load current per channel for the DO910?
A1: Each channel supports up to 40 mA, but the internal resistance must exceed 270 Ω for optimal performance.

Q2: Can the DO910 operate in Zone 0 hazardous areas?
A2: No, it is certified for Zone 1/Zone 2 (EEx ia II C). Zone 0 requires additional barriers.

Q3: How is short-circuit detection handled?
A3: The module pulses the channel at 1 kHz to limit current and reports the fault via PROFIBUS diagnostics.

Q4: Is external power required for the DO910?
A4: No, it is powered via the S900 termination unit.

Q5: Can the DO910 be used with non-ABB control systems?
A5: Yes, it is compatible with any PROFIBUS-DP master using the provided GSD files.

Q6: What is the debounce time for input signals (DX910 reference)?
A6: Configurable between 10 ms, 20 ms, or 50 ms via parameterization.

Q7: How are substitute values configured during faults?
A7: Options include “0”, “1”, or “last valid value” for each channel.

Q8: What is the operating temperature range?
A8: Typically -20°C to +60°C (refer to datasheet for exact limits).
