Count-match Output
When there is a match between a count value on a channel and a count compare value,
the pulse output is prepared to notify external device. The pulses width can be
changed in the allowable range
0 - 104.45msec. The pulses output to the channels separately.
The pulse width is common to all channels, and is determined by setup data. The
initial pulse width is 0, so even if there is a match between count value and count
compare value, the pulse will not output. When you use it you must set the pulse
width.
The signal output section has an open collector configuration based on Optocoupler
isolation. It can drive 35VDC 50mA load too. The equivalent circuit is described in
[External Input and Output].
