Connection of analog output loads (Voltage, current)
Fig. 51: Connection example
The following measuring ranges can be configured
on page 491:
Voltage
Current
Current
Only the channels 0...3 and 8...11 can be configured as current output (0 mA...20 mA or 4
mA...20 mA).
The function of the LEDs is described under Displays.
Unused analog outputs can be left open-circuited.

I/O configuration
The module does not store configuration data itself. It gets its parameterization data from the
master device of the I/O bus (CPU or communication interface module) during power-up of the
system.
That means replacing I/O modules is possible without any re-parameterization via software.

If the external power supply voltage via UP/ZP terminals fails, the I/O module
loses its configuration data. The whole station has to be switched off and on
again to re-configure the module.
