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)
