System Compatibility
The INR-244-755 is primarily designed for use within SMC’s modular automation architecture. Confirmed or commonly reported compatible systems include:
- SMC EX250 / EX260 / EX500 series fieldbus systems
- SMC SY / VQC / VFS series valve manifolds
- Siemens S7-300 / S7-1200 / S7-1500 PLC panels (as auxiliary supply)
- Mitsubishi MELSEC iQ-R / Q series control cabinets
- Omron NX / NJ series machine automation controllers
Compatibility depends on your specific system configuration. Contact us for a pre-purchase compatibility review.
Selection Guide
Use the following criteria to determine whether the INR-244-755 is the right power supply for your application:
- Step 1 — Confirm output requirements: Match the output voltage and current to your SMC manifold or valve island specifications.
- Step 2 — Check mounting format: Verify DIN rail or panel-mount compatibility with your control cabinet layout.
- Step 3 — Assess load profile: Ensure the rated output current covers peak inrush current of all connected devices.
- Step 4 — Review certifications: Confirm CE, UL, or other regional certifications required by your project.
- Step 5 — Evaluate lead time vs. equivalent: If OEM lead time is unacceptable, request a verified equivalent from Konmask.

Replacement & Compatibility FAQ
Q: Is the INR-244-755 still in production?
A: Production status varies. Contact us for current availability and lead time from SMC or verified equivalent sources.
Q: Can I use a generic power supply as a replacement?
A: Only if the electrical specifications (voltage, current, ripple) and connector pinout are identical. We strongly recommend a verified OEM equivalent to avoid system faults.
Q: Do you offer a warranty on replacement units?
A: Yes — new OEM units carry manufacturer warranty. Refurbished and equivalent units carry a 90-day Konmask functional warranty.
Q: Can you supply the INR-244-755 with a certificate of conformity?
A: Yes, documentation is available upon request for all stocked units.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock items typically have a 2–6 week lead time depending on source.
