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.
