Replacement & Compatibility FAQ
Q: Can I replace 140DDO36400 with 140DDO36400C without software changes?
A: Yes. The conformal-coat variant is a direct hardware drop-in with identical I/O mapping and firmware behavior.
Q: Is the 140DDO36400 still in production?
A: Schneider Electric has transitioned some Quantum series modules to end-of-life status. Konmask maintains stock of both new and certified-refurbished units. Contact us to confirm current availability.
Q: Can this module work with a Modicon Premium or M340 rack?
A: No. The 140DDO36400 is exclusively designed for the Modicon Quantum (140 series) backplane and is not cross-compatible with Premium or M340 platforms.
Q: What is the difference between sourcing (PNP) and sinking (NPN) output?
A: Sourcing outputs supply current to the load (common negative/0V). Sinking outputs sink current from the load (common positive/24V). Verify your field device wiring before selecting a replacement.
Q: Do you provide a test report or certificate of conformance?
A: Yes. A functional test report and certificate of conformance (CoC) are available upon request for all units.
