Expansion Connector 2
This connector is for input and output with external equipment. It is used in combination with the teaching feature. It
makes it possible to control the machine using signals from an external device and to send signals from the machine to an
external device with specified timing. For information about how to perform control using expansion connector 2, refer
to "Chapter 4 The Teaching Feature."

Internal Circuit Schematic
The outputs connected to the input ports are
assumed to be contactless outputs such as
transistors. When you are making connec-
tions that use mechanical contact (such as
switches or relays), use microcurrent de-
vices.
Ensure that the leakage current when a
contactless circuit connected to the input
ports is off is 1 mA or less per input port.
