NOTE!
The external voltage supply for the digital input/output module 12-channel and the voltage sup-
ply for controlling the digital inputs of this module must be switched on/off with a common dis-
connecting device (common electrical circuit).
CAUTION!
At maximum load, the temperature may exceed 60 °C at the terminals.
As a result the insulation of the cable may be damaged.
The cable must be heat resistant up to at least 80 °C.
CAUTION!
Connecting the external voltage supply DC 24 V via the terminals at the front
(terminals “GND“ and “+24V“):
Ensure that the polarity is correct!
CAUTION!
The voltage of the digital outputs depends on the external voltage supply.
In case of undervoltage, no voltage is provided at the digital outputs.
Observe the technical data for the external voltage supply!
