Signal Conditioning Modbus RTU DAT3011

General Description

The Signal Conditioning Modbus RTU DAT3011 is a unique design signal converter. It is an analog input and analog output Signal Conditioner with a 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 a RS485 MODBUS RTU.
