RTD to Modbus, Potentiometer, Resistance to Modbus converter
DAT3014 RS485
The RTD, Potentiometer and Resistance to Modbus converter DAT3014 Modbus is a 4 channel RTD, Potentiometer and Resistance input Modbus converter. The DAT3014 Modbus converts the RTD, Potentiometer and Resistance analog signal to a 16 bit digital format. The data is transmitted by the Modbus RTU protocol on RS485. There are several options on the RTD, Potentiometer and Resistance input on the DAT3014 Modbus such as is Pt100, Pt1000, Ni100, Ni1000 0-500Ohms and 2000 Ohms. The DAT3014 Modbus is also available in the RS485 Modbus format.
