Product overview

The SRE series IO products use a 100M backplane bus, with a scan cycle as short as 125μs. A single coupler can be expanded to 2048DI, 2048DO, 512AI and 512AO at most, which is suitable for high-speed, high-precision, multi-detection point real-time bus control applications. The SR series supports more than 70 types of modules. In addition to traditional digital and analog input/output modules, it also provides position acquisition modules, Ethernet/IP master modules, MODBUS master/slave modules, DeviceNet master/slave modules, and stepper motor drive modules, which can easily integrate fieldbus devices including CANopen, DeviceNet, Ethernet/IP, etc. into the EtherCAT system.
