Function
This isolated barrier is used for intrinsic safety applications.
The device supplies 2-wire SMART transmitters in a
hazardous area, and can also be used with 2-wire SMART
current sources.
It transfers the analog input signal to the safe area as an
isolated current value.
Digital signals may be superimposed on the input signal in the
hazardous or safe area and are transferred bi-directionally.
Selectable output of current source, sink mode, or voltage
output is available via DIP switches.
If the HART communication resistance in the loop is too low,
the internal resistance of 250Ω between terminals6 and8
can be used.
Test sockets for the connection of HART communicators are
integrated into the terminals of the device.
