6.44 Analogue output module UR20-4AO-UI-16-DIAG-HD
AnalogueoutputmoduleUR20-4AO-UI-16-DIAG-HD(OrderNo.1506930000)
The analogue output module UR20-4AO-UI-16-DIAG-HD
can control up to 4 analogue actuators with ±10V, ±5V,
0 ... 10V, 0 ... 5V, 2 ... 10V, 1 ... 5V, 0 ... 20mA or 4 ... 20mA.
The resolution is 16bit per channel. An actuator can be con-
nected to each connector in a 2-wire or 4-wire connection
(IDC), the internal switching is carried out automatically. The
output range is dened using parameterisation. A status LED
is assigned to each channel. The outputs are supplied with
power from the output current path (I
OUT
). The outputs are
decoupled from the system bus I
SYS
, but there is no potential
isolation to the output current path I
OUT
.
The module provides individual channel diagnosis with chan-
nel related error messages.

ATTENTION
Product can be destroyed!
The outputs as well as the sense-lines of the AO modules
must not be used as power outputs!
Please regard the following notes when wiring,
to avoid perturbation effects and to ensure pro-
per function of the module.
▶ Use shielded analogue lines only and earth
them on both ends. In case of potential dif-
ferences between the ends, you should
earth one end only.
▶ Always use shielded twisted pair lines
when connecting the actuators.
▶ Shielding: Apply the cable schield to the
functional earth directly on entering the
cabinet; on applications without cabinet
apply it to a shield bus.
