Module for the emergency shutdown function*
When the 24 V DC signal is interrupted, the I/P module executes
the respective safety function, depending on the mechanical
construction.
The positioner output 1 is depressurized, and the valve is moved
to the safe position. In case of a double-acting actuator, output
2 is additionally pressurized.
The emergency shutdown module works independently of the
mother board, i.e., all information from the final control element
is available in the control system at any time.
