MTL3046B: Smart Transmitter Interface for Hazardous Areas
The MTL3046B safely powers and communicates with smart transmitters in explosive areas. It provides 15V at 20mA to run your device. It also repeats the 4-20mA signal perfectly for your safe-area systems. You can calibrate and test transmitters from your computer. It works with most smart transmitters available today.
