Product Details

• CS1D Duplex System Overview
• The CS1D Duplex System is a highly reliable Programmable Controller (PLC) System. By providing duplex CPU Units, Power Supply Units, and Communications Units, the CS1D can continue control operations and be restored with no need to shut down the entire system in the event of an error or malfunction. Select from either of two Duplex Systems: A Duplex CPU System or a Single CPU System. A Duplex CPU System includes two CPU Units. Even if an error occurs in the active CPU Unit, the standby CPU Unit continues operation, thus preventing a system shutdown. The Single CPU System uses a single CPU Unit. In either System, duplex Power Supply Units or Communications Units can be used to provide high reliability in the event of an error in the power supply system or the active Communications Unit. It is now possible to select a Duplex CPU with duplex Connecting Cables (Dual I/O Expansion System), as well as the previously available Duplex CPU with a single Connecting Cable (Single I/O Expansion System).
