Replacement & Compatibility FAQ
Q: Can the 140CPU67260 replace the 140CPU67160 directly?
A: Yes. The 140CPU67260 is a higher-memory variant and is a direct drop-in replacement for the 140CPU67160 in the same Quantum rack slot.
Q: Is the 140CPU67260 compatible with Unity Pro?
A: Yes, in compatibility mode. Unity Pro XL supports Quantum CPUs in legacy compatibility mode, allowing program upload/download without full migration.
Q: Can I use this CPU with Modicon M340 or M580 I/O modules?
A: No. The 140CPU67260 is exclusively compatible with Modicon Quantum (140xxx series) I/O and backplane hardware.
Q: What is the difference between 140CPU67260 and 140CPU67260S?
A: The “S” suffix denotes the hot-standby variant, which includes additional hardware for redundant CPU configurations. The standard 140CPU67260 is a single CPU module.
Q: Do you provide a warranty?
A: Yes. All units carry a minimum 90-day functional warranty. Extended warranty options are available — contact us for details.
