5.9. Control-Outputs
Four safety-related HTL control outputs are available at the screw terminal [X2 | CONTROL OUT].
Each of the output performs complementary (OUT1, /OUT1 to OUT4, /OUT4).
The switching points and conditions are adjustable by Parameters (see chapter 7.4.5 and 7.4.6 )
In normal state (no error, no switching conditions active) the non-inverted outputs offers LOW level
and the inverted outputs offers HIGH level. During HIGH state, the output level is about 2 V below
the supply voltage connected to terminal [X3 | 24V IN]. Each output has a push-pull output stage and
short circuit protection. When switching inductive loads, additional external suppression measures
are recommended.
In case of errors all outputs are LOW (no more inversion between Out_ and /Out_).
The connection to the Analog-Output is only safe if the following device is capable to detect the
error state of the safety unit.
pluggable 8-pin screw terminal [X2]
Example: Control-Output with inductive load (Relay)
OUT4 and /OUT4 safety-related wired
