Why Engineers Specify This Model
- Redundancy-Ready Architecture — Two 140CPS12420C modules can be installed in parallel on a single Quantum rack, providing N+1 power redundancy without additional hardware.
- 24 VDC Input Compatibility — Directly accepts 24 VDC from standard industrial power rails, eliminating the need for intermediate AC/DC conversion in DC-powered panels.
- Proven Quantum Platform Integration — Designed exclusively for the Modicon Quantum backplane, ensuring zero compatibility risk and full firmware alignment.
- Hot-Swap Capable — Supports replacement under power in redundant configurations, enabling maintenance without system shutdown.
- Long Field Life — Schneider Electric’s Quantum series is a mature, globally supported platform with a decades-long installed base and available spare parts.
- Compact Single-Slot Footprint — Occupies only one backplane slot, preserving rack space for I/O and communication modules.

Application-Specific FAQ
Q: Can I use two 140CPS12420C modules in the same rack for redundancy?
A: Yes. The Quantum backplane supports dual PSU slots. Installing two 140CPS12420C modules provides N+1 redundancy — if one fails, the other maintains full backplane power without interruption.
Q: Is the 140CPS12420C compatible with all Quantum backplane sizes?
A: It is compatible with the 140 XBP series backplanes (6, 10, and 16 slot). Always verify the specific rack model against Schneider Electric’s compatibility matrix before ordering.
Q: What is the difference between 140CPS12420 and 140CPS12420C?
A: The “C” suffix denotes a conformal-coated PCB version, offering enhanced protection against humidity, dust, and corrosive atmospheres — recommended for harsh industrial environments.
Q: Can this module be replaced while the system is running?
A: In a redundant dual-PSU configuration, yes — the failed module can be swapped without powering down the rack. In a single-PSU configuration, the rack must be de-energized before replacement.
Q: Do you provide documentation or datasheet with the order?
A: Yes. A copy of the Schneider Electric product datasheet and installation guide is available upon request. Contact [email protected].
