9.2.9 Options
Module for the emergency shutdown function
Supply voltage 24 V DC (20 ... 30 V DC) (galvanically
isolated from input signal)
Safe position is activated
when Explosion protection
voltage < 5 V see certificate
(operating instructions)
A separate 24 V DC signal is normally applied to the emergency
shutdown module, which connects through the signal from the
microprocessor to the I/P module.
When the 24 V DC signal is interrupted, the pneumatic module
executes the respective safety function, depending on the mechanical
construction.
The positioner output Y1 is depressurized, and the valve is moved to
the safe position. In case of a double-acting actuator the second
output Y2 is additionally pressurized.
IMPORTANT (NOTE)
The emergency shutdown module can only be used with
pneumatics with the safe position “fail-safe”.
The emergency shutdown module works independently of the mother
board, i.e. all information from the final control element is available in
the supervisory process control system at any time.
Digital position feedback with proximity switches
1)
Two proximity switches for independent position signaling. Switching
points adjustable between 0 … 100 %
Current circuits acc. to DIN 19234 / NAMUR
Supply voltage 5 ... 11 V DC
Signal current < 1 mA Switching state logical “0“
Signal current > 2 mA Switching state logical “1“
