Description:

• Ex-output isolation amplifier with external power supply for a 2-channel HART transparent 2-channel output isolation amplifier for standard DC current signals. It can be used to transmit and isolate standard signals with a current of 4 to 20 mA from the safe zone to Ex zones 0, 1, and 2.
• Using a relay contact (NO), you can access status and error messages.
• The component can be set up with the help of common FDT and DTM software.
