, PWM, PWM
I
)
■
Semiconductor outputs, with diagnostic capability
%QX0.00...07 positive switching (high side), short-circuit and overload protected
can be configured as ... switching voltage 10...32 V DC
switching current max. 4 A
output frequency max. 100 Hz (depending on the load)
■
PWM outputs, diagnosis via current feedback
PWM frequency max. 250 Hz
mark-to-space ratio 1...99 %
resolution depends on the PWM frequency
load current max. 4 A
integrated pull-down resistor (4.7 k
Ω
) to trigger valves (Danfoss type PVH)
■
Current-controlled outputs, diagnosis via current feedback
load current 0,1...4 A
load resistance min. 3
Ω
(at U
B
= 12 V DC)
min. 6
Ω
(at U
B
= 24 V DC)
setting resolution 1 mA
control resolution 5 mA
accuracy ± 2% FS
Overload protection max. 5 minutes (at 100%)
(valid for all outputs)
Internal relay outputs Normally open contacts in series to 2 groups of 4 semiconductor outputs.
for electrically isolated Sustained forcing by means of hardware and additional controlling
deactivation of the outputs by means of user program.
The relays must always be switched without load!
total current max. 12 A per group
switching current 0.1...15 A
overload current 20 A
number of operating cycles
≥
10
