• ◆ Approvals: UL 508, CSA C22.2 No 142, cUL, and FM Class 1 Division 2 suitable for hazardous locations.
• ◆ Altitude: Safe for installation up to 5000m (16404ft).

Frequently Asked Questions (FAQ)

• Q: What is the main difference between 140DAO84210 and the fully isolated 140DAO84000?
  A: The 140DAO84210 groups outputs into four isolated groups of four, whereas 140DAO84000 provides individual channel isolation. This offers a cost‑effective solution when group isolation is sufficient.
• Q: What are the per‑group current limits?
  A: Each group of four channels supports up to 4A rms continuous, with the total module current not exceeding 16A rms.
• Q: How does the module indicate a blown fuse or loss of field power?
  A: The red Fault LED (F) illuminates, and specific group fault conditions are signalled via the front‑panel diagnostics.
• Q: What is the off‑state leakage current at 230V?
  A: Maximum leakage is only 2.5mA rms at 230V, ensuring minimal power draw when outputs are off.
• Q: Can I mix different AC voltages across the four groups?
  A: Yes, each group is isolated, so you can supply different voltages (e.g., 115V and 230V) to different groups as long as they stay within 83‑253V AC.
• Q: Does the 140DAO84210 support fast‑switching applications?
  A: Absolutely. With ≤0.5ms turn‑on and turn‑off times, it suits high‑speed AC switching tasks.
