RTD and Resistance to RS232 converter DAT3019 RS232

General Description

The RTD and Resistance to RS232 converter DAT3019 RS232 is an 8 Channel RTD, and Resistance input RS232 converter. The DAT3019 RS232 converts the RTD and Resistance analog signal to a 16 bit digital format. The data is transmitted by the RS232 ASCII protocol on RS-232. There are several options on the RTD and Resistance input on the DAT3019 RS232 such as is Pt100, Pt1000, Ni100, Ni1000 0-500Ohms and 2000 Ohms. The DAT3019 RS232 is also available in the RS485 Modbus format.
