Selection Guide
Use the following criteria to confirm the 51303926-100 is the right module for your application:
- ✅ Your system is a Honeywell TDC 3000 or TPS platform
- ✅ You require 4–20 mA or 1–5 V analog input signal acquisition
- ✅ Your card file chassis accepts standard TDC 3000 I/O cards
- ✅ You need channel-to-channel isolation for signal integrity
- ⚠️ If your system is Experion PKS or C300, a different module family is required – contact Konmask for the correct part
- ⚠️ If you need HART protocol support, verify the revision suffix (-150 or later may be required)

Replacement & Compatibility FAQ
Q: Can the 51303926-100 replace the 51303926-150?
A: They are from the same series but different revisions. In most cases they are functionally interchangeable, but firmware version and chassis slot compatibility should be verified with your system engineer.
Q: Is this module compatible with Experion PKS?
A: No. The 51303926-100 is designed for TDC 3000 / TPS architecture. Experion PKS uses a different I/O module family. Contact us for the correct Experion equivalent.
Q: Do you supply new or refurbished units?
A: Konmask supplies both new OEM stock and professionally refurbished units. All units are tested and documented. Please specify your preference when ordering.
Q: What is the lead time?
A: In-stock units typically ship within 1–3 business days. Lead time for sourced units is 5–15 business days depending on availability.
Q: Can I get a datasheet or wiring diagram?
A: Yes. Contact [email protected] with your part number and we will provide available technical documentation.
