2.3 I / O Terminal Wiring Diagram
The I / O terminal is located on the serial communication cable. If the equipment is
connected to external signals or to drive external equipment, it is necessary to use this
terminal to connect with external equipment. The drawing of the terminal is shown as
below, and the serial number and definition of the terminal are shown in the table
。
Note
①
: It depends on the voltage of the power supply connected to the serial port
cable.
Note
②
: The valid level value can be set, and the default is 24VDC.
