GL7-L/P Logic/Pulse Module GL 7000 Data Acquisition Equipment

Quantity
Add Quotation


This is a digital input module capable of measuring the timing of the
control signals or the number of pulses.

In Logic mode: sampling in 1MS/s (1μs) to 1S/hr. (1hr.).
It is able to measure the timing of the control signals as the relay
by this module. It allows to measure simultaneously both the timing
of control signals and an analog waveform using other analog input modules.
In Pulse mode: sampling in 10kS/s (100μs) to 1S/hr.(1hr.) It is able to count
the number of pulses for measuring such as the encoder output, a rotation
speed, or flow rate. It allows to measure simultaneously both the number of
pulses and an analog waveform using other analog input modules.
