Replacement & Compatibility FAQ
Q: Can I use 2MLQ-RY1D (without CC) as a direct replacement?
A: Possibly. The CC suffix typically denotes a specific connector variant. Physical and electrical verification is required before substitution.
Q: Is the 2MLQ-RY1D-CC compatible with Experion PKS?
A: No. This module is designed for TDC 3000 / TPS. Experion PKS uses a different I/O architecture. A migration assessment is required.
Q: Do you offer exchange / repair services?
A: Yes. Contact us with your defective unit details for a repair or exchange quote.
Q: What is the lead time for new units?
A: Typically 3–10 business days depending on stock availability. Contact us for real-time inventory status.
Q: Can Konmask verify compatibility before I purchase?
A: Absolutely. Send us your system details and we will confirm compatibility at no charge.
