Product Details 

140CPU65260 is high‑performance Unity‑based CPU for Schneider Modicon Quantum platform,runs IEC61131‑3 programs with 266MHz processing core,4MB user program memory,optimized for large‑scale process control projects.

It occupies two slots on Quantum backplane. Native interfaces include 10/100Mbps Ethernet,Modbus Plus,Modbus RS232 and USB port. Supports hot‑standby redundant configuration via dedicated fiber synchronization link,realizes bumpless switch‑over between primary and standby CPU. Front‑panel LCD display provides direct status diagnosis without programming tool.

Compatible with S908 RIO and EIO EtherNet/IP remote I/O architecture. Note:140CPU65260C is conformal‑coated version for corrosive harsh environment. This model is discontinued; recommended replacement is BMEP584040 Modicon M580 CPU. Widely used as replacement spare‑part for legacy large‑size redundant Quantum control systems in chemical,power,metallurgy and water‑treatment industry。
