0 Power supply with +24 VDC output voltage
l When dimensioning the power supply take into account the currents at the
outputs (max. 1 A per output).
1 Emergency switch
l It must be ensured that the outputs do not carry any voltage and the inputs do
not receive a HIGH signal when the switch is actuated.
2 Digital inputs with normally−open contact
3 Digital outputs with consumer
4 System bus (CAN) ( ^ 56)
5 PE connection (6.3 mm AMP connector)
l Connect the PE connection with the conductive rear panel of the control
cabinet. This ensures a troublefree operation of the terminal extension.

Danger!
Install an additional mains isolation if
ƒ the terminal extension is connected to a host,
ƒ a safe mains isolation (double insulating distance) according to
EN 50178 is necessary.
