Applications

• Electronic test and maintenance
• Transmitter calibration and switch test
• Loop set-up and diagnostics

Temperature Instrumentation and Loop Maintenance

• Dual Readings
  Provides simultaneous frequency output and mA measurement for transmitter and loop maintenance
• 24V Loop Power Supply
  Energizes transmitters and control loops.
• Automatic Switch Test
  Captures open/closed trip values providing a fast and highly accurate “safety system” check.
• HART Resistor
  Can be switched into the loop when required by a HART digital communicator and avoids the inconvenience of carrying a 250 Ω resistor.

IDOS Flexibility

• Intelligent Digital Output Sensor (IDOS)
  Universal Pressure Modules are available from 10 in H2 O to 10,000 psi (25 mbar to 700 bar).
• Automatic Switch Test
  IDOS modules can be used with any compatible instrument; for example, a DPI 812 RTD loop calibrator can become a fully featured pressure calibrator.
• Plug and Play
  Modules are interchangeable between instruments, requiring no set-up or instrument calibration.
