CJ1W-IDP01
High-speed Input Unit
Latches input pulses as short as 50 µs.
• Reads pulses that are too fast for normal I/O,
such as is often requried for signal exchange with
inspection devices.
• Reads pulse widths (ON time) as short as 0.05 ms.
• Inputs stored in the internal circuits are cleared in
I/O refresh period.
