Electric
The RUMC22B7 is a part of Schneider Electric's Modicon M340 automation system, specifically an Ethernet-based Communication micro-module. This micro-module is designed to manage communications to a total of up to four Ethernet-based external devices, such as an OPC server, a web-server, etc. It also has four RS232/RS422/RS485 serial ports and provides connection to ProfiNET, Modbus TCP/IP, IEEE 802.3 Ethernet, and DH+ Ethernet. The module is also very small, allowing it to fit inside smaller control cabinets and be easily maintained.
