Characteristic
Description
Output turn off time (
1
)
Typical 50 μs (with a load current = 1 A)
Note:
turn off time increases if load current < 1 A.
Galvanic insulation
Yes
Short circuit protected
Yes, maximum short circuit current 3 A.
Fail / no load detection
No
Grounded load
Yes (high side switching)
IEC61131-2 compliant
Yes
PWM (Pulse Width Modulation)
Yes
1
Indicated times only apply with a resistive load. Indicated times
change if the load has a capacitive component.

PWM signal specifications of the digital outputs
The PWM signal is defined by the NYCe 4000 software through the PWM
frequency parameter specified in Hz, and the duty cycle parameter specified
in %. These two parameters are internally converted to pulse duration "a" and
pulse pause duration "b" (see
fig. 9-8 "PWM signal specification parameters"
) which can only have a discrete increment step size. The
