3.4.2 Connecting binary inputs and outputs (connector X31)
Connector X31 provides eight binary inputs or outputs (e.g. for controlling external actu-
ators / sensors).
You can program the binary inputs / 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 interference-voltage-proof.
• 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 minimum core cross section of 0.25 mm
2
(AWG23) and
a maximal core cross section of 1 mm
2
(AWG18). IEC 60999 does allow clamping
without conductor ender sleeves.
• Choose the type and core cross section of the connected cable in dependency of 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 78.

• To avoid damage to the MOVI-PLC
®
controller and to preserve the specified function
of the binary inputs and outputs, the supply voltage must be present on pins X31:1/2
when using the inputs and outputs. If the supply voltage is stopped, you must turn off
all other current supplies to X31:1 ... 12, e.g. the DC 24 V from switches and sensors
at the binary inputs.
• To avoid the danger of maximum voltage peaks, you may not connect inductive loads
to the supply voltage or to the binary inputs or outputs without free-wheeling diodes.
