FAQ – Frequently Asked Questions
What is the difference between simplex and redundant modes?
Simplex uses one power path. Redundant uses two for backup. Choose redundant for critical processes.
Can I mix HART and non-HART devices on this card?
Yes. Enable HART per channel. Non-HART channels work normally.
How do I know if the fuse has blown?
The card reports an open-loop condition. Check LED status. Replace the 2.0 A fuse if needed.
What happens if ambient temperature exceeds 70°C?
Accuracy may drop. Keep temperature below 70°C. Use cooling fans if necessary.
Is this card compatible with third-party PLCs?
It works best with Emerson DeltaV. For other PLCs, check HART protocol support.
How long does shipping take?
We ship via FedEx (3-5 days), UPS (3-7 days), or DHL (2-4 days). Express options available.
What is your return policy?
Returns accepted within 30 days. Product must be unused. Contact us for RMA number.
