Product Details

The Schneider 140CPU67160S Unity safety hot standby processor module is a SIL3 certified dual-slot redundant core control unit of Modicon Quantum PLC automation platform, developed for safety-critical industrial applications requiring uninterrupted operation and safety instrumented control. This safety modicon quantum cpu module adopts a 32-bit RISC processor running at 266MHz clock frequency, equipped with 1024kB built-in RAM, and supports memory expansion via PCMCIA card to expand program and file storage space. It runs Unity Pro XL safety software and complies with IEC61508 SIL3 safety standard, supporting safety function programming, comprehensive safety fault diagnosis and safety data synchronization between redundant CPUs. It fully supports IEC61131-3 standard programming languages for both safety and non-safety logic. The module integrates dedicated multi-mode fiber optic hot standby port for real-time safety data synchronization between primary and standby CPUs. When the master CPU fails, the standby unit can automatically complete bumpless switchover to keep the safety system running continuously. This CPU also carries one 10/100Mbps Ethernet port, one Modbus serial port and one Modbus Plus communication port, supporting data exchange with local I/O modules, S908 remote I/O stations, distributed I/O stations, safety I/O modules, HMI touch screens and other field automation equipment. It can support up to 2 local racks, maximum 31 S908 remote I/O stations and 63 distributed I/O stations over Modbus Plus network. The onboard Ethernet port supports TCP/IP communication, web diagnostic function and Ethernet remote I/O scanning. The module comes with a 2×16 LCD backlight display and key switch for memory protection, supporting high-speed interrupt input, event time stamping and high-precision counter functions. A hardware watchdog timer continuously monitors program execution status and triggers safety protection actions automatically once abnormal operation occurs. It occupies two adjacent slots on Quantum backplane rack and must be paired with another identical 140CPU67160S module to build SIL3 hot standby redundant safety system. This original Schneider product was discontinued, widely stocked as spare replacement parts for maintenance and upgrade of legacy SIL3 safety instrumented systems. It is widely deployed in power, petrochemical, natural gas pipeline, metallurgy and manufacturing plants as the redundant safety core controller for critical safety instrumented systems.
