Detection of Pulse I/O Modules
• The CJ2M CPU Unit detects the configuration of mounted Pulse I/O Modules each time the power
supply is turned ON. An error will not occur even if the number or models of the mounted Pulse I/O
Modules are different from the last time the PLC was operated.
• A fatal error (too many I/O points) will occur and the CPU Unit will not operate if three or more Pulse
I/O Modules are mounted.

Additional Information
• Pulse I/O Modules can be connected only to CJ2M CPU Units. They cannot be used with
CJ2H CPU Units.
• The pin arrangement of the I/O connected on the CJ2M-MD211 (sinking outputs) is compatible
with the built-in I/O connector on the CJ1M-CPU2@ CPU Unit.
