Swtiching I/O Modules of the WAGO-I/O-SYSTEM 750

No test pulses when test pulse duration = 0 ms!
If you have set the test pulse duration of the digital power output to "0 ms (off)",
the PROFIsafe I/O module does not test the digital output cyclically (e.g., for an
short circuit or defect). The PROFIsafe I/O module only tests the digital power
outputs during a change of state. In this case, the digital power output only meets
the requirements for SIL3 according to EN 62061 or PL e according to EN ISO
13849-1 if the safe control switches off both digital power outputs at least every
24 hours at the same time for at least 1 second in an automatic test. The
PROFIsafe I/O module executes a test during the disconnection time and is
therefore able to detect errors at the outputs. Take into account the total time
needed to transfer the process image to the PROFIsafe I/O module when
configuring the disconnection time.
You can operate the interference-free I/O modules of the -I/O-SYSTEM 750 in
conjunction with the PROFIsafe I/O module 750-666/000-003 and safety controls
in safety applications.
Loads that are supplied and switched by the interference-free I/O modules of the
WAGO I/O SYSTEM 750 can be safely switched OFF in conjunction with the
PROFIsafe I/O module 750-666/000-003.
The loads are switched OFF exclusively by the digital power outputs of the safe
PROFIsafe I/O module 750-666/000-003 switching off the field supply voltage
for the interference-free I/O modules of the WAGO-I/O-SYSTEM.
The 24V field supply voltage is transferred by engaging the power jumper
contacts on the located on the housing sides of the interference-free I/O modules.
While the PROFIsafe I/O module 750-666/000-003 makes switching the 24V
field supply voltage possible, the I/O modules of the WAGO-I/O-SYSTEM 750
transfer the 24V field supply voltage through a bilateral connection. Switching off
the voltage by the PROFIsafe I/O module switches OFF all loads of the linked
modules supplied with this voltage.
