Connecting binary inputs and outputs (connector X31)
Connector X31 provides eight binary inputs or outputs (e.g. for controlling external
actuators / 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 interrupt service routine is processed is less than 100 ms.
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 maximal core cross section of 1 mm
2
.
•
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 chapter 8 Technical Data on
page 65.

The supply voltage must be present on pins X31:1 and X31:2 for using the binary inputs
and outputs.
