Products Description
Red Lion RM100-EM-8TX Ethernet Expansion Module

Module Feature
RM100-EM-8TX belongs to Red Lion RM100 rack system ethernet expansion module. It provides 8 channels of 10/100BASE-TX copper ethernet interface with RJ45 connector. Hot-swappable structure allows replacement without powering down the whole rack. Each ethernet channel has electrical isolation protection to suppress industrial site electromagnetic interference. Supports TCP/IP, Modbus TCP and other common industrial network protocols, can connect PLC, RTU, HMI and various field instruments. Metal module shell adapts to harsh industrial workshop environment for continuous stable data transmission.
Working principle
The module is inserted into RM100 chassis slot and communicates with backplane bus. It receives and forwards network data packets through 8 RJ45 ports, realizes multi-node network expansion. Isolation circuit isolates field side surge and interference to protect internal mainboard. It performs data exchange between backplane bus and external ethernet field network.
Onboard components
Main control PCB, RJ45 port group, network isolation circuit, backplane connector, status LED indicator, surge protection circuit, power regulation chip.
LED indicators
Power LED, Link/Activity LED for each ethernet port.
Hardware self-diagnosis
Port link fault, overvoltage, undervoltage, over temperature, ESD surge detection, record port communication error statistics.
Programming software
Red Lion Crimson software for network parameter configuration, port monitoring and firmware update.
