Key Features:
- Software-configurable communication parameters including baud rate, data bits, and stop bits
- LED status indicators for power, communication, and fault alerts
- Hot-swappable for easy system maintenance without shutdown
- Automatic baud rate detection for simplified device pairing
- Supports system-level redundancy (Modbus RTU does not support module-level redundancy)
- Long-distance communication up to several kilometers via fiber optic converter
Applications:
- Data collection and remote monitoring for SCADA systems
- Integration of PLCs, HMIs, frequency converters, and instruments in industrial networks
- Master or slave node in Modbus RTU networks for connecting third-party devices
- Controller-to-controller data transfer using COMLI protocol
