Overview
The SRR series plug-in I/O modules adopt a structure that combines a coupler and an I/O module. The coupler connects the expandable I/O module to the real-time industrial Ethernet system. The backplane uses the S-Link bus, and the coupler module is responsible for field bus communication, thereby realizing the function of real-time data exchange between various I/O modules and the coupler/controller. The SRR series plug-in I/O modules are rich in variety and have high real-time performance, providing users with high-speed data acquisition, optimized system configuration, simplified field wiring, and improved system reliability.
