The signal names and descriptions of each terminal
The signal names and descriptions of each terminal are described as follows.
Refer to "Functions of the I/O Signal" (page 7-5) for the detailed functions.
• 24V DC (–) and COM1 are common via a choke coil. Be careful not to generate
a potential difference.
• 0 V for the analog monitor output is isolated from COM1. It is common to the FG
terminal for the AC power supply.
• 24V DC terminal is a dedicated power supply terminal for the monitor specified
by KEYENCE ONLY. Do not use to power other external devices.
The control I/O can be selected from the binary output of the measured value or
the tolerance judgment output depending on the setting.
Refer to "I/O" (page 5-20) for the setting details.
