HART® SNAP I/O analog modules are designed to provide communication with other Highway Addressable Remote Transducer (HART) current loop devices.

HART SNAP I/O modules include the SNAP-AIMA-iH current input module and the SNAP-AOA-23-iH current output module.

If you are controlling HART SNAP I/O modules through a SNAP PAC controller running a PAC Control strategy, you do not need this technical note nor the software development kit (SDK).

If you are not using PAC Control and are developing or adding to a .NET or Mono custom program to communicate with HART SNAP I/O modules, you will need this technical note and the SNAP PAC .NET HART SDK.
