Galvanic isolation

(1) Functional galvanic isolation for connection of SELV or PELV electrical circuits.
NOTE!
The external voltage supply for the digital input/output module 32-channel and the voltage supply for
controlling the digital inputs of this module must be switched on/off with a common disconnecting device
(common electrical circuit).

Connection diagram

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!
The connection for the external voltage supply DC 24 V (terminals "GND" and "+24V" at the front)
is not protected against reverse polarity.
Reverse polarity may damage the module.
 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 technical data for the external voltage supply!
CAUTION!
Signals to the several digital inputs must have the same ground reference.
Otherwise undefined signal levels may occur.
 Ground reference via GND terminal required!
