3.6.4 Technical data – safety outputs
Safety outputs
Suitable for inputs according to EN 61131-2, type 1
Output level in OFF-state
Voltage level < 5V
Current level < 1 mA
Test pulses
ohmic load, maximum 0.5 ms
maximum 1.25 ms
Interval between 2 test pulses
typical 500 ms
minimum 250 ms
The load has to provide a mechanical or electrical inertia in order to tolerate the test pulses.
Max. output current
DC load 2 A, derating see
Derating curves (page 23)
DC13 load without external free-wheeling diode 1 A
DC13 load with external free-wheeling diode 2 A
Max. total current for device 9 A, derating see
Derating curves (page 23)
Times
Internal delay time
(for calculating the Watchdog time)
10 ms
Reaction times see
