The Omniflex Teleterm M3 (Model C2330B-11-0) is an intelligent, programmable remote terminal unit (RTU) designed for the demands of modern wireless telemetry. Whether deployed in water treatment plants, remote pump stations, or energy monitoring sites, the M3 provides a cost-effective way to bring field data to the desktop over cellular GPRS networks.

Multi-Protocol Connectivity

One of the core strengths of the C2330B-11-0 is its ability to serve as a high-performance communication bridge. It features an integrated 10/100 Ethernet port and a serial RS-232/485 port, supporting both Modbus TCP and Modbus RTU protocols simultaneously. This allows the unit to poll local Modbus sensors and transmit the aggregated data to a central SCADA system or a cloud platform via GPRS. The unit supports SMS messaging for critical alarm alerts, ensuring immediate notification of field anomalies.

Versatile I/O and Edge Intelligence

Despite its compact footprint, the Teleterm M3 is equipped with 12 universal I/O channels. These channels are highly flexible and can be individually configured as digital inputs, analog inputs, or digital outputs. This internal I/O capability, combined with IEC 61131-3 (ISaGRAF) programming support, enables the RTU to perform edge logic—processing data locally before transmission to save bandwidth and improve response times.

Reliable Remote Monitoring

• Data Logging: Internal memory allows for extensive time-stamping of data, ensuring no information is lost even during GSM network outages.
• Wide Supply Voltage: The 9-30V DC input range makes it ideal for solar-powered installations or battery-backed systems.
• Rugged Design: Built for industrial environments with an operating temperature range of -20°C to +60°C.
• Cloud Integration: Fully compatible with Omniflex Data2Desktop service for instant web-based monitoring and reporting.

Typical Applications

• Remote reservoir and water level monitoring
• Cathodic protection monitoring in gas pipelines
• Power and energy usage tracking in distributed facilities
• SMS alarm notification for unmanned substations
