HART, FOUNDATION Fieldbus & Profibus PA Support:
The ADT295 Field Device Communicator is a versatile, all-in-one solution for configuring, calibrating, diagnosing, and managing HART®, FOUNDATION™ Fieldbus, and Profibus PA instruments. Designed for industrial process applications, it supports transmitters, positioners, and other field devices used across the oil & gas, chemical, power, and process industries.
FREE DD library updates – no fees or subscriptions:
Additel doesn’t charge a fee or a subscription for DD library or firmware updates — there’s no support contract required just to keep the communicator current. With pre-installed libraries supporting over 2,600 HART, FOUNDATION Fieldbus, and Profibus PA devices, the ADT295 is ready to communicate with a wide range of field instruments right out of the box.
0.01% RD + 1.5 μA Accuracy & No External Power or Resistors Required:
Designed to streamline field calibration, the ADT295 supports autoranging voltage measurement, current measurement, current output, and an integrated 24 V loop power supply for testing and calibrating AI and AO cards — all from a single handheld. Voltage and current readings are accurate to 0.01% RD, and the loop power supply outputs 24 V ±5% with up to 30 mA of drive capacity, enough to power a transmitter directly during testing without sourcing external power.
Two Ports. Zero Confusion:
The ADT295 puts its electrical connections in a simple two-port layout on top of the unit, removing the confusion of hooking up to devices in the field. Technicians can connect quickly and get to the work at hand.
