Function

This isolated barrier is used for intrinsic safety applications.

The device supplies 2-wire transmitters in the hazardous area.

The device transfers the analog input signal to the non-hazardous area as an isolated current value.

Digital signals may be superimposed on the input signal on the field side or control side and are transferred bi-directionally.

The output is selected as a current source, current sink, or voltage source via DIP switches.

If the HART communication resistance in the loop is too low, the internal resistance can be used.

Test sockets for the connection of HART communicators are integrated into the terminals of the device.
