DM10 diagnostics module
The process data acquisition system (PADU8) is used for troubleshooting analog and digital
signal. The process data acquisition system is designed as an optional component. If the
PADU8 is not included, the signals can be read out with the aid of an oscilloscope, for example,
at measuring sockets. The interface description and the connector assignment are provided in
the List Manual and in the circuit diagram.

Functions
The DM10 diagnosis module performs the following functions:
● Monitoring the auxiliary voltages of the internal 1P24 and 1N24 power supply.
● Monitoring the external voltage 2P24_1 and the optional external voltage 2P24_2 for
● Monitoring the auxiliary contacts of the 24 V DC miniature circuit-breakers.
● Output of eight binary control signals. The logic state of the signal in each case is indicated
● Output of eight analog signals to the following signal receivers:
● Supply of the digital and analog signals to measuring sockets for simplified diagnosis with
