Analogue Output 23AO60
Application
During initialization and operation the board
Analogue control outputs for sequential or carries out a number of tests. If a fault occurs it
closed-loop control, display instruments, is reported to the communication unit. All fault
measurement recorders etc. can be connected conditions impairing the function of the board
by the analogue output board 23AO60. The are displayed as common fault signal with a red

voltage/current ranges. The output format
unipolar, bipolar or live zero (4 … 20 mA) will
be configured by software parameter.
The following output ranges can be configured
by onboard switches:
• ± 2.5 mA ± 1.25 V DC
• ± 5.0 mA ± 2.50 V DC
• ± 10 mA ± 5.0 V DC
• ± 20 mA ± 10 V DC
• 4 … 20 mA
Characteristics
Each output has a digital to analogue converter
(DAC), which converts the digital value into an
analogue signal. The DAC has a resolution of
11 bit plus sign. A received output value keeps
stored until a new value is received. The output
channels are set to 0 % after power up or reset Fig. 1: Block diagram
of the board. Analogue output board 23AO60
The output channels are potential isolated from
the power supply, but not between the two
channels. The board is equipped with a serial interface to
the RTU211 system bus (Wired OR-Bus). While
The micro-controller on the board processes all using the analogue output board in an RTU560

bus. All configuration data and processing
parameters are loaded from the communication
unit via the system bus.
