Product Details

140CPU67260 is high‑end multimode Unity hot‑standby processor for Schneider Modicon Quantum platform,PowerPC 604e 266MHz RISC architecture,designed for large‑scale high‑availability process‑control projects. It occupies two adjacent slots on Quantum backplane.

Built‑in MT‑RJ multimode fiber hot‑standby sync port realizes hardware hot‑standby redundancy for primary‑standby CPU,maximum fiber transmission distance up to 4km with bumpless switch‑over between master and standby; on‑board Ethernet,Modbus Plus,RS232 and USB interfaces; supports PCMCIA memory card for program and file storage expansion. Front‑panel LCD display supports local status check and fault diagnosis without programming tool.

Compatible with S908 RIO and EIO EtherNet/IP remote I/O architecture,supports up to 63 distributed I/O stations. Note:140CPU67260C is conformal‑coated version for corrosive harsh environment. This model is discontinued; recommended replacement is BMEH584040 Modicon M580 redundant CPU. Widely used as replacement spare‑part for legacy large‑size redundant Quantum control systems in chemical,power,metallurgy and water‑treatment industry。
