Modbus Isolated Output
DAT3024ISO
The DAT3024ISO is an isolated version of the DAT3024, as the four analog output channels are isolated from the other. The output channels are isolated from the Modbus RTU signal and Power Supply. This greatly improves the ground loop interference. The DAT3024ISO accepts high-speed Modbus RTU RS485 signals (115200 Mbps) from the field. It converts the signal into four independently isolated outputs, either active current, passive current, or voltage output. The output is scaleable to be anything between 0-20 mA or 0-10V.
The default Modbus Baud rate is 38400, and the high-speed Baud rate is 115200 Mbps. The analog output is high resolution and able to provide the third decimal place, which is 4.000 mA or 0.000Volt. Isolation is 1500Vac, making the DAT3024ISO suitable for industrial applications.
