HIMHART Smart HART Loop Interface & Monitor
Brand: Yokogawa Electric CorporationThe HIMHART Loop Interface and Monitor unlocks the full potential of new and in-place smart HART multivariable transmitters and valves.
Converts HART to 4-20 mA Signals: The HIM allows up to three additional Analog process variable measurements from a smart device with no additional process penetrations or wiring.
Take Full Advantage of “Legacy” Instruments: The HIM lets you leave trusted (and paid for) smart HART transmitters and valves in place, yet still take advantage of all the information they have to offer.
Features- "Break Out" up to three analog signals proportional to a HART primary, second, third or fourth variables of multivariable transmitters
- High/Low process and loop diagnostic alarms
- Normal or Burst HART Modes
- Sets up as a Primary or Secondary Master, or in "Listen" Mode
- Large, 5-digit display
- Isolated output channels
