3-1 I/O Specifications
3-1-1 Input Specifications
General-purpose Input Specifications
Note 1. The power supply voltage on the line driver side is 5 V ±5%.
2. The input time constant can be set to 0, 0.5, 1, 2, 4, 8, 16, or 32
µs.
When it is set to 0 ms, the delay due to internal components results in an
ON delay of 30
µs max. for IN0 to IN5 (2 µs max. for IN6 to IN9) and an
OFF delay of 150
µs max. for IN0 to IN5 (2 µs max. for IN6 to IN9).
