FAQ
Frequently Asked Questions (FAQ)
Q1: Does the DO571 module have short-circuit or overload protection?
A1: No, external fast-blow fuses or circuit breakers are required.
Q2: What is the maximum current per output channel?
A2: Each channel supports up to 2.0 A for resistive loads.
Q3: Is there isolation protection on the outputs?
A3: Yes, there is galvanic isolation between the output groups and the rest of the module.
Q4: Can the module be mounted both horizontally and vertically?
A4: Yes, but vertical installation requires load derating to 50% per group.
Q5: Is DO571 suitable for high switching frequency applications?
A5: No, it is not recommended. Max switching frequency is 1 Hz for resistive loads.
Q6: Are there cable length limitations when using the module?
A6: Yes, up to 500 m for shielded cables, and 150 m for unshielded.
Q7: Is a protective earth (PE) connection required?
A7: Not required for the module itself, but functional earth (FE) grounding is recommended for EMC.
Q8: Are the output signals visually indicated?
A8: Yes, each channel has a yellow LED that lights up when the signal is high.
