We provide two types of Remote I/O modules: Serial (RS-485/Modbus RTU) and Ethernet (Modbus/TCP). The Serial modules enable reliable communication via RS-485 with Modbus RTU protocol, ideal for long-distance data transmission in industrial environments. The Ethernet modules utilize Modbus/TCP, offering fast, scalable network integration for real-time monitoring and control over LAN or the Internet. Both types support multiple input/output configurations, ensuring flexibility and reliability for industrial automation and remote monitoring solutions.
