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.

With both online and offline operating modes, the ADT295 communicates directly with installed field devices during operation while also supporting calibration, testing, and troubleshooting in metrology laboratories, instrument shops, and maintenance facilities. Integrated loop power and advanced diagnostic capabilities eliminate the need for external power supplies, resistors, and other accessories, allowing technicians to complete more tasks with a single handheld device.

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.
