CJ1W-OD202 Transistor Output Unit (8 Points)
* Terminal numbers A0 to A8 and B0 to B8 are used in the external connection and terminal-device variable diagrams. They are not printed on
the Units.
Note: Although 16 I/O bits (1 word) are allocated, only 8 of these can be used for external I/O.

Circuit Configuration
• When overcurrent or line disconnection is detected, the ERR indicator will light, and the corresponding bit (two points per bit) in the Basic
I/O Unit Information Area (A050 to A069) will change to TRUE.
• The signal names of the terminals are the device variable names.
The device variable names are the names that use "Jxx" as the device name.
External connection
and terminal-device
variable diagram
• When wiring, pay careful attention to the polarity of the external power supply. The load may operate incorrectly if the polarity is reversed.
• The signal names of the terminals are the device variable names.
The device variable names are the names that use "Jxx" as the device name.
