Selection Guide
Use the following criteria to confirm the SIRON 19H01088-0350 Y449 is the right module for your application:
- Step 1 – Verify Part Number: Confirm the full part number including suffix (Y449) matches your BOM or existing installation
- Step 2 – Check Coil Voltage: Match the relay coil voltage to your control circuit (24 VDC / 110 VAC / 230 VAC)
- Step 3 – Confirm Contact Rating: Ensure the relay contact load (A/V) meets your output device requirements
- Step 4 – Validate Mounting: Confirm DIN rail width and module slot compatibility with your existing panel
- Step 5 – Check Revision: Y449 suffix indicates a specific hardware revision — do not substitute with a different suffix without engineering review
- Step 6 – Quantity & Lead Time: Contact us for bulk pricing and availability confirmation

Replacement & Compatibility FAQ
Q: Can I replace the Y449 with a Y448 or Y450 revision?
A: Possibly, but hardware revisions may include changes to firmware, connector pinout, or contact ratings. Always verify with SIRON’s revision change documentation before substitution.
Q: Is this module compatible with non-SIRON PLCs?
A: Relay modules are generally interface-agnostic at the contact level, but backplane and bus communication may be SIRON-specific. Confirm with your system integrator.
Q: Do you offer a datasheet for this module?
A: Yes. Contact support@konmask.com with your inquiry and we will provide available technical documentation.
Q: What is the lead time if the item is out of stock?
A: Typical sourcing lead time is 5–15 business days depending on availability. Contact us for a real-time stock check.
Q: Can I return the module if it doesn’t fit my system?
A: We accept returns within 14 days for unused, unopened items. Please contact support before returning.
