LK-G-M-NO4-E
4 Input/Output Terminals
* COMs for output of pin Nos. 5 and 36 are common.
* COMs for input of pin Nos. 12 and 40 are common.
* The cord color is the wire color of the extension connector cable (OP-51657).
Caution
• Precautions for Wiring
Part of each input/output circuit of the LK-G Series is internally common. Be sure that no
potential difference is generated between the common terminals due to the potential dif-
ference between wires or external devices.
Refer to "Precautions for Wiring" page 4 for details.
• NPN type
COM OUT and COM IN are common via a choke coil. Also, 24 V DC (–), COM OUT and
COM IN of the 12-pin I/O terminal block are all common via a choke coil. Be careful not to
generate a potential difference.
• PNP type
COM IN and 24 V DC (-) are common via a choke coil. Also, 24 V DC (-), and COM IN of
the 12-pin I/O terminal are common via a choke coil. Be careful not to generate a potential
difference.COM OUT and COM OUT of the 12-pin I/O terminal are common.
