The Galvanically Isolated Analog Output (AO) FTAs isolate up to sixteen 4-20 mA signals that can drive current-to-pressure (I/P) transducers, position actuators, or any load of 870-ohms or less from the associated Analog Output IOP. In addition, these FTAs incorporate filters to allow connection to HART field devices, and provide a connector for use with an external HART multiplexer system.

PIN

1 thru 16 – Combined 4-20mA / HART signals for Channels 1 through 16, respectively.

17 thru 20 – Ground.
