Key Features

1. Dual Independent Modbus RTU Master Channels
   • Operates as a Modbus RTU master with two separate channels, allowing simultaneous management of two distinct slave networks.
   • Each channel is fully programmable and can be configured for different communication modes and parameters.
2. Versatile Communication Interfaces
   • Supports RS-232 for short-distance direct connections, RS-422/RS-485 for multi-drop networks up to 2000 meters, and dial-up/radio modem for long-distance or wireless applications.
   • Compatible with a wide range of Modbus RTU slave devices, including remote I/O, sensors, meters, and controllers.
3. High-Speed & Flexible Data Exchange
   • Supports baud rates up to 115200 bps for fast, efficient data transfer.
   • Each channel can send/receive analog or discrete data using standard Modbus commands (e.g., Read Coils, Read Registers), with up to 250 bytes per command.
4. Robust Industrial Design
   • Features a compact, vertical-mount form factor that fits standard GE 90-30 PLC racks.
   • Built with industrial-grade components to withstand vibration, shock, and wide temperature fluctuations for reliable operation in harsh environments.
5. Diagnostic LEDs & Easy Configuration
   • Equipped with dedicated LED indicators for power status and channel activity, enabling quick on-site troubleshooting.
   • Configured via standard GE programming software, with data mapped directly to the PLC’s reference tables for seamless integration.
