CJ1W-IDP01 Quick-response Input Unit (16 Points)
• With quick-response inputs, pulse inputs shorter than the CPU Unit's cycle time can be read by the CPU Unit.
• The pulse width (ON time) that can be read by the Quick-response Input Unit is 0.05 ms.
• Inputs read by the internal circuits are cleared when inputs are refreshed.
* 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.
