Absolute Process Instruments API 4001 G L _ RTD input transmitter. Fully isolated.

Features:

  • Convert Temperature to DC Output
  • Zero and Span for Output
  • Automatic Leadwire Compensation
  • Input and Output LoopTracker® LEDs
  • Output Test Button
  • Built-In Loop Power Supply

Applications:

  • Convert Output From RTD Sensor for PLC Input, Control and/or Validation
  • Interface an RTD with Panel Meters, PLCs, Recorders, Data Acq., DCS, & SCADA Systems

The API 4001 G L accepts an RTD temperature input and provides an optically isolated and linearized DC voltage or current output. The sensor type, temperature range and output range are factory set and can be specified as required. This provides an economical solution when a temperature sensor signal must be converted to a DC signal.

The temperature input is linearized and amplified, and then passed through an optocoupler to the output stage. Full 3-way isolation (input, output, power) make this module useful for ground loop elimination, common mode signal rejection, and noise pickup reduction.

Sourcing mA Output

The API 4001 G L has a 20 VDC loop excitation supply for the output. This power supply can be used to power a passive mA device.

LoopTracker API

exclusive features include LoopTracker LEDs (green for input, red for output) that vary in intensity with changes in the process input and output signals. They provide a quick visual picture of your process loop at all times and can greatly aid in saving time during initial startup and troubleshooting.

Output Test

An API exclusive feature includes an output test button to provide a fixed output (independent of the input) when held depressed. The output test greatly aids in saving time during initial startup and/or troubleshooting. The test output level is factory set at 50% of output span.

Mounting

The API 4001 G L plugs into an industry standard 8-Pin octal socket sold separately. Sockets API 008 and finger-safe API 008 FS allow either DIN rail or panel mounting.
