Pneumercator Internal Dual Modbus RTU Interface Card - (SKU: 900665-5-5) is an OEM plug-in card providing two independent, industry-standard RS-485 Modbus RTU interfaces for advanced automation and data integration in tank management consoles. Designed for TMS4000, TMS3000, TMS2000, TMS2000A, TMS2000W, LC2000, TMS1000, and TX1064-2, the card enables high-density data acquisition, BMS/SCADA polling, and remote status reporting.

Dual Isolated Modbus Channels: Both ports are fully isolated to prevent ground loop interference, support simultaneous polling from two host automation systems, and connect up to 4000 ft of cable (Belden 9841 or equivalent recommended). DIP switches enable address and baud rate selection (9600 or 38400 baud), with onboard line termination for multi-drop networks.

Plug-and-Play Hardware Configuration: Requires no console software programming; all settings managed via DIP switches for slave address and baud rate. LED indicators on card provide TX (transmit) and RX (receive) status diagnostics. Program up to 64 registers per read command, with fast register update rates (0.8–1.2 secs typical).

Applications: Used for real-time tank data acquisition, alarm/event reporting, and status integration with any SCADA, PLC, or building management system requiring robust, isolated RS-485 Modbus RTU communications in hazardous or industrial environments.
