When you need access to these additional HART variables and diagnostic data, but don’t have a HART based DCS or asset manager, consider the HIM HART Interface Module. The HIM polls any HART compatible instrument and allows you to break out any HART dynamic variable or diagnostic bit and covert it to a 4-20mA signal or alarm, respectively.  The HIM allows you to retransmit up to three dynamic HART variables and gives you one or two alarms that can be tied to most any diagnostic bit or dynamic variable. Additionally, the HIM has redundant MODBUST RTU outputs optional. The HIM is approved for installation in Class I Div 2/Zone 2 areas and is configured via a free Windows PC program and sets up in just a few minutes.

Key Attributes:

  • Polls any HART instrument and breaks out additional HART variables and diagnostics
  • Class I Div 2/Zone 2 approval
  • -40 to 85C ambient operating temperature
