Description
Protection
Thermal overload
protection
–
Isolation voltage
between channel and
other circuits
none
–
Cable length
max. 30 m
Only valid for unshielded connection cables.
Cables over 30 m in length must be shielded
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 result in oscillation of
the output.
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.
