Pneumercator Internal Modbus RTU Interface Card for TMS3000 - (SKU: 900552-10) is an OEM plug-in interface module that adds industry-standard Modbus RTU RS-485 serial communications to Pneumercator TMS3000, TMS4000, and compatible tank gauge consoles. This card provides easy, reliable connection to any building management system (BMS), SCADA, PLC, or remote monitoring equipment supporting the Modbus RTU protocol.

Comprehensive Data Access: Supports continuous readout of tank product and water levels, status and alarm conditions, leak/point level sensor states, and input/output closures. All real-time TMS data is available for polling using standard Modbus mapping.

Industrial-Grade Connectivity: Installs in a secure slot within the TMS main enclosure with a 3-wire, half-duplex RS-485 bus (Belden 9841 or equivalent recommended) supporting cable runs up to 4000 feet. Onboard DIP switches allow for quick setup of slave address and baud rate (9600 or 38400 bps), with built-in line termination for multi-drop networks.

Plug-and-Play Integration: Provides a plug-in terminal block for easy wiring, LED indicators for transmit/receive diagnostics, and requires no console software programming—just set address and baud rate and connect to your host device.

Applications: Ideal for integration with facility controls, energy management systems, remote telemetry, or automated reporting. Used in petroleum terminals, chemical plants, generator farms, and industrial automation sites needing real-time tank data acquisition.
