Key Features

1. Dual Independent Modbus RTU Master Channels
   • Equipped with two fully independent master channels, allowing simultaneous communication with two separate Modbus RTU networks.
   • Each channel is individually configurable for baud rate, parity, data bits, and stop bits, supporting speeds up to 115.2 kbps.
2. Multi-Protocol & Multi-Topology Support
   • Supports RS-232, RS-422, and RS-485 physical layers, enabling compatibility with diverse slave device interfaces.
   • Configurable for multi-drop networks, direct point-to-point connections, dial-up modems, and radio modem links for long-range communication.
3. Comprehensive Data Exchange Capabilities
   • Transmits and receives analog (16-bit) and discrete (binary) data using standard Modbus RTU commands (e.g., Read Coils, Read Holding Registers).
   • Each channel can issue multiple commands to slaves, with each command handling up to 250 bytes of contiguous data.
4. Robust Industrial Design & Isolation
   • Provides 2500 V DC isolation between communication channels and the PLC backplane, protecting against electrical transients and ground loops.
   • Built with EMI shielding and industrial-grade components for reliable operation in electrically noisy and vibration-prone environments.
5. Seamless PLC Integration & Diagnostics
   • Plugs directly into standard GE 90-30/90-70 PLC racks, requiring no additional adapters.
   • Equipped with dedicated LEDs for power, module status, and channel activity, enabling quick on-site troubleshooting.
   • Configured via standard GE programming software for network setup, slave mapping, and fault diagnostics.
