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.

* There are two slots for the option modules. Any combination of different
option modules is possible. However, identical option modules cannot be
combined.
Limit switch
The limit switch can either be equipped with proximity switches
or with potential-free microswitches.
