The Signal Conditioning Modbus RTU DAT3011 is a unique design signal converter. It is an analog input and analog output Signal Conditioner with an RS485 Modbus RTU Slave port. The DAT3011 can convert Thermocouples, RTD's, Resistance, mA Volts and Potentiometers into two Isolated 4-20mA outputs and three digital outputs. The DAT3011 also has three digital input terminals and one digital output and two relay outputs.
The DAT3011 can be set up as a Signal converter, a Signal Splitter, a Trip Amplifier, and a Dual Signal Conditioner.
The input, output ports, power supply and RS485 ports are isolated from each other up to 1500Vac.
The DAT3011 converts the analog signals to a 16 bit digital format and can provide an analog output whilst transmitting the data on an RS485 MODBUS RTU.
