Feature Value Description
Protection Thermal overload
protection
–
Isolation voltage
between channel
and other circuits
none
–
Cable length max. 30 m Applies to unshielded connection cables. At
cable lengths of more than 30 m it is
necessary to use shielded cables.
Shared points
between the
channels
AGND AGND is the reference potential for all
analogue outputs.
Calibration
frequency
12 months Maintenance of accuracy class
Permissible load
types
–
Ohmic and capacitive loads
Largest capacitive
load
10 µF Higher capacitive loads may cause the output
to oscillate.
Load impedance
range
≥ 1 kΩ –
Overload protection Short-circuit-proof Current limitation from approx. 22 mA (at 25°C
ambient temperature)
Output response during power supply switching on and switching off processes
No supply voltage AI (I) to AGND:
< 40
Ω
Low-resistance output
During device boot-
up
–
The analogue output is not active during
device boot-up. Deviations from the zero
value during switching on are approx. ≤ 1.5%
of the signal range (voltage connected to open
output for approx. 150 ms).
During temporary
interruptions
–
The analogue outputs are disconnected and
low-resistance in the case of temporary
interruptions to the power supply of > 10 ms.
Behaviour in stop mode
Voltage output
–
Can be configured in CODESYS. Either the
last valid value is used or 0 V is used.
