Field of application

The active barrier is used for transmission and galvanic isolation of 4 to 20 mA/HART signals. The device has an active / passive current input to which a 2- or 4-wire transmitter can be connected directly. The output of the device can be operated actively or passively. The current signal is then available to the PLC / controller or for further instrumentation at pluggable screw or optional push-in terminals.

  • 1-channel active barrier, wide-range power supply

  • Transmission and galvanic isolation of analog 0/4 to 20 mA signals

  • Optionally intrinsic safe [Ex-ia] signals from hazardous area

  • Bidirectional transmission of HART® communication signals

  • Feeding or not feeding input for 2- or 4-wire instruments 

  • Active or passive signal output

  • Ambient temperature range: -40 … 60 °C (-40 … 140 °F)

Benefits

  • Wide range power supply of 19.2 to 253 V AC/DC

  • Quick and easy wiring thanks to plug-in terminals

  • Optional for safety-oriented applications up to SIL 2 (SC3) in accordance with IEC 61508

  • Optional installation in Ex Zone 2

  • Compact housing width with 17.5 mm (0.69 in) for efficient use of space

  • Option for installation rotated by 180° (terminals for power supply at top or bottom)
