Function

This signal conditioner provides galvanic isolation between field circuits and control circuits.

The device can be used in emergency shutdown applications with HART positioners.

Via the logic input the positioner is energized or de-energized (emergency shutdown).

Independent of the status, a second input enables HART communication with the positioner. With this the asset management system can request for example diagnostic information or can initiate a partial stroke test.

The HART communication also works with de-energized positioner.

If the device is operated via Power Rail, additionally a collective error message is available.
