Product Details 

140CPU67160 is standard Unity hot‑standby redundant CPU for Schneider Modicon Quantum platform,without conformal coating,designed for high‑reliability industrial process control scenarios. It adopts PowerPC 603e processor at 266MHz,built‑in 1024kB internal RAM,supports PCMCIA memory card for program and file storage expansion.

This CPU integrates MT‑RJ multimode fiber port dedicated for hot‑standby synchronization,realizes bumpless automatic switchover between primary and standby CPU,ensuring continuous system operation. It comes with Modbus Plus,Modbus,USB native interfaces and supports up to 6 optional communication modules to build multi‑network industrial control architecture.

Note: Hot‑standby mode disables fast tasks,interrupt tasks and auxiliary tasks,only cyclic master task is available. It supports massive remote distributed I/O capacity,suits large‑scale DCS and PLC control system. Mainly used as replacement spare‑part for redundant Quantum PLC system in chemical,power,metallurgy and water‑treatment projects. Functionally compatible with 140CPU67160C,140CPU67160C is conformal coated version for harsh environment.
