RTD to Modbus, Potentiometer, Resistance to Modbus converter
DAT3014 RS485
The DAT3014 Modbus Converter is a 4-channel input module designed for RTDs, potentiometers, and resistance sensors. It converts analog signals into a 16-bit digital format and transmits the data over an RS-485 network using the Modbus RTU protocol.
Supported sensor types include Pt100, Pt1000, Ni100, Ni1000, as well as resistance ranges of 0–500 Ω and 0–2000 Ω. This flexibility makes the DAT3014 suitable for a wide range of industrial temperature and resistance measurement applications.
The device ensures accurate, stable measurements and is available in an RS-485 Modbus RTU format, making it easy to integrate into PLCs, SCADA systems, and other Modbus master devices.
