Replacement & Compatibility FAQ
Q: Can PM861K01 replace PM863K01 directly?
A: In most cases yes, but PM861K01 has less application memory. Verify your Control Builder project’s memory usage before substituting.
Q: Is PM864K01 backward compatible with PM863K01?
A: Yes. PM864K01 is a drop-in upgrade and supports all PM863K01 hardware configurations and firmware versions.
Q: Can I use PM863K01 in a redundant CPU setup?
A: Yes. PM863K01 supports hot-standby redundancy when paired with a TB840/TB840A redundancy module and a second PM863K01.
Q: What is the difference between PM863K01 and PM863AK01?
A: The “A” suffix typically denotes a hardware revision with minor improvements (e.g., extended temperature range or updated ASIC). Both are functionally equivalent for most applications.
Q: Do you supply new or refurbished units?
A: We supply both. All units are clearly labeled and tested. New units come with full ABB packaging; refurbished units include our 12-month warranty.
