Binary inputs
• The digital inputs are electrically isolated by optocouplers.
• The permitted input voltages are defined according to IEC61131.
+13V–+30V = "1" = contact closed
-3V–+5V = "0" = contact open
Binary outputs
• The digital outputs are electrically isolated by optocouplers.
• The digital outputs are short-circuit proof but not external-voltage-proof.
• The maximum permitted output current is 150mA per digital output. All eight digital
outputs can be operated simultaneously with this current.
