Frequently Asked Questions

• Q: What does “7” in DO571 mean?A: The “7” indicates relay output type with 8 channels. Different numbers (like DO5xx) mean different output types (transistor, triac, etc.).
• Q: Can I mix AC and DC loads on same module?A: Yes. Each relay is independent. You can have 24 V DC on channel 1 and 230 V AC on channel 2. No problem.
• Q: What is the maximum switching current?A: 2 A per channel resistive load. For inductive loads (motors, contactors), use external snubbers or derate to 1 A.
• Q: Is DO571 compatible with AC500 (non-eCo) CPUs?A: Yes, it works with both AC500 and AC500-eCo CPUs. Same backplane compatibility.
• Q: How do I select between DO571 and DO524?A: Choose DO571 for relay outputs (multi-voltage, 2A). Choose DO524 for fast transistor outputs (24 V DC, 0.5A) if you need high-speed switching.
• Q: Does it come with connector included?A: Yes, screw terminal connector is attached. No need to order separately.
