Replacement & Compatibility FAQ
Q: Is GJR2374800R0210 the same as 81EA11E?
A: Yes. GJR2374800R0210 is the ABB catalog part number for the 81EA11E module. Both refer to the identical hardware.
Q: Can I use ABB AI810 as a direct replacement?
A: Not directly. The AI810 is designed for the S800 I/O bus (AC 800M platform) and requires a bus adapter and configuration changes to work in an Advant OCS rack.
Q: Do you supply refurbished units?
A: Yes. All refurbished units undergo full functional testing and are supplied with a test report. Lead time is typically 3–7 business days.
Q: What is the minimum order quantity?
A: MOQ is 1 piece. Volume pricing is available for orders of 5+ units.
Q: Can you help with cross-brand migration from Advant OCS to a newer platform?
A: Yes. Contact our engineering team for a free migration assessment and BOM comparison.
