RTD to Modbus, Potentiometer to Modbus and Resistance to Modbus converter DAT3014

General Description

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 ASCII protocol on RS-232. 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.
