Various types of counts
[Prescaling]
The input pulse can be converted to any values and displayed.
[Dual phase addition/subtraction by individual input]
The counting range can be from positive to negative.
However, settings are in the positive range.
[Addition-Subtraction]
Counts can be selected for positive or negative display.
Dual output with alarm output
Dual setting is possible with alarm output.
Alarm values are values prior to reaching preset values.
High-speed response with 10 kcps
The input response frequency for this class is a maximum of 10
kHz. Input operational speed can be adjusted to switch to 30, 200,
1 k, or 10 kHz.
IP65
Membrane is used to protect from operation with wet or dirty
hands, A special cover is also provided as an option to enhance the
protective structure.
