• ◆ 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: Can I use the 140DAO84000 with different AC voltages on different channels?
  A: Yes, each output is isolated, so you can mix voltages (e.g., 115V and 230V) across channels as long as each stays within 20‑253V AC.
• Q: What is the maximum total current for the module?
  A: The module supports up to 16A rms total, but observe the per‑point limits (4A for 24‑115V, 3A for 200‑230V) and the 4A continuous sum for any four points.
• Q: How are the outputs protected against transients?
  A: Each output includes an internal RC snubber (dv/dt 400V/µs) and the module uses a 5A associated fuse for additional protection.
• Q: What is the off‑state leakage current at 230V AC?
  A: Maximum leakage is only 2.5mA rms at 230V, ensuring minimal power drain when outputs are off.
• Q: Does the 140DAO84000 provide isolation between outputs and the backplane?
  A: Yes, it features full isolation between channels and the bus, enhancing safety in mixed‑voltage environments.
• Q: What diagnostic indicators are available on the front panel?
  A: You get 16 green LEDs for individual output status, plus a green Active LED and a red Fault LED for quick troubleshooting.
