Safety Function

The safety function of the X-HART module includes the following points:

 HART Deactivation of one channel: If the module is shut down, the HART channels are

safely deactivated in accordance with SIL 3 (HART channels de-energized).

 HART Filtering: HART write access to HART transmitters or sensors is locked in accordance

with SIL 3. If the HART filtering function is deactivated on the HART module, the

corresponding analog input or output channel is writeable.

Reaction in the Event of a Fault

If a fault occurs, the module adopts the safe state.

The X-HART module is interference-free to the analog input or output modules connected in the

same circuit.

The module activates the Error LED on the front plate.

Scope of Delivery

The module must be installed on a suitable connector board to be able to operate. If a Field

Termination Assembly (FTA) is used, a system cable is required to connect the connector board

to the FTA. Connector boards, system cables and FTAs are not included within the scope of

delivery.
