Digital output module UR20-4DO-PN-2A (Order No. 1394420000)
The digital output module UR20-4DO-PN-2A can control up
to 4 actuators each with a maximum of 2 A. One actuator
can be connected to each connector in a 2-wire or 3-wire
+ FE connection. A status LED is assigned to each channel.
The outputs are supplied with power from the output current
path (I
OUT
).
Each channel can be switched between positive and nega-
tive switching. This allows, among other things, a switch in
rotational direction if an DC motor is connected between
two outputs. For this purpose, an output byte is reserved for
the physical outputs, and each channel is assigned two bits
in this byte. The switching characteristics of each output
are set in the low nibble of the byte. If a bit is set, the cor-
responding channel has positive switching, if it is 0 then
it has negative switching. The outputs are switched in the
high nibble. Example: If you write the value 185decimal
(10111001binary) in the output byte, channel1 is set to
24V, channel 2 is set to GND, channel3 is deactivated and
channel4 is set to 24V.
The module is protected against external voltages between
0V and the operating voltage.
