Assembly / Installation Notes
3.3.2 Connecting binary inputs and outputs (terminal X31)
Terminal X31 provides eight binary inputs or outputs (e.g. for controlling external
actuators / sensors).
You can define the binary inputs and outputs in the PLC editor of the MOVITOOLS
®
MotionStudio software.
Binary inputs • The binary 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
Interrupt inputs • You can use binary inputs X31:6 to X31:10 as interrupt inputs. The response time
until the ISR (interrupt service routine) is processed is less than 100 μs.
Binary outputs • The binary outputs are electrically isolated by optocouplers.
• The binary outputs are short-circuit proof but not protected against external voltage.
• The maximum permitted output current is 150 mA per binary output. All eight binary
outputs can be operated simultaneously with this current.
Cable specification • Only connect cables with a core cross section of minimum 0.25 mm
2
(AWG23) and
maximum 1 mm
2
(AWG18). Clamping without conductor end sleeves is possible in
accordance with IEC 60999.
• Choose the type and core cross section of the connected cable depending on the
required cable length and the load expected from your application.
For more information on binary inputs or outputs, refer to section 8 Technical Data on
page 82.

• To prevent the MOVI-PLC
®
control card from being damaged and to ensure the
specified function of the binary inputs and outputs is achieved, the supply voltage
must be applied to X31:1/2 when using the binary inputs and outputs. If the supply
voltage is switched off, you must switch off all other voltages at X31:1 ... 10 , e.g.
DC 24 V of switches and sensors at the binary inputs.
• To prevent dangerous voltage peaks from occurring, do not connect inductive loads
to the supply voltage or the binary inputs or outputs without free running diodes.
