Product Overview
The Schneider 140CHS32000 Hot Standby Splitter Kit is a specialized accessory used to implement high-availability configurations in Modicon Quantum PLC systems. Specifically designed for coaxial cable-based redundancy, this splitter kit enables seamless communication and synchronization between an active Quantum CPU and its hot standby counterpart.
In a Hot Standby configuration, the system utilizes a pair of Quantum CPUs — one actively controlling the process, and the other maintaining an identical, synchronized state. Should a failure occur in the primary CPU, the backup CPU instantly takes over, ensuring zero interruption in the control process. The 140CHS32000 splitter kit facilitates this by allowing both CPUs to share the communication path over coaxial media — a robust and EMI-resistant connection option ideal for many industrial environments.
Designed with industrial durability and ease of integration in mind, the 140CHS32000 Hot Standby Splitter Kit is an essential part of any redundancy scheme where coaxial cabling is required or preferred. It supports reliable data transmission, quick switchover, and uninterrupted system operation — making it a trusted choice in sectors such as manufacturing, energy, transportation, and critical infrastructure.
