GL7-L/P
Logic / Pulse Module

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.
