4 channel RTD input to Modbus RTU DAT10014
DAT10014
The DAT10014 Modbus RTU Converter is a 4-channel slave device designed for acquiring signals from RTDs, potentiometers, and resistance sensors and converting them into Modbus RTU data. This makes it an efficient solution for integrating multiple sensors into SCADA systems, PLCs, and other Modbus-compatible equipment.
Configuration is simple via front-panel DIP switches, which allow the user to set the Modbus address, baud rate, parity, and communication mode (RTU or ASCII). For more advanced setup, the DAT10014 can also be configured using the free DAT3000–10000 configuration software, providing fast and flexible programming options.
Each of the four channels can be individually managed, providing flexible data acquisition in a single compact unit. The device provides 1500 Vac galvanic isolation between input, output, and power supply, ensuring safe and reliable operation even in electrically noisy environments. It operates from a 10–30 VDC power supply, making it suitable for a wide range of industrial applications.
