Analog Multi-Window Comparator

Analog Multi-Window Comparator

Convert analog input to 8-point output; input supports three types of voltage ranges.

Convert analog input to 8-point output Input supports 3 types of voltage ranges ■■■■ Features ■■■■ Compare analog voltage input Convert 1 analog input to 8 ON/OFF outputs, comparing with an accuracy of ±0.01V (10mV). The input voltage can be switched between "0-5V," "0-10V," and "4-20mA" using a switch. Set MAX and MIN ON ranges for each output Individual Max and Min settings can be made for each of the 8 outputs. You can set each of the 8 outputs individually or overlap arbitrary outputs, allowing for flexible judgment conditions.

4ch Measurement Active Filter 'T-L/HPF04C'

4ch Measurement Active Filter 'T-L/HPF04C'

Active filters for measurement with specific characteristics for each channel, made to order.

It is possible to set the cutoff frequency for each channel and choose between low-pass and high-pass filters, making it a completely custom-made product tailored to the customer's requirements. It can be designed to have characteristics that perfectly match the intended use. This tool has a very wide range of applications, including noise reduction and bandwidth limitation during A/D conversion. It has a wide allowable range for power supply voltage and relatively low current consumption, making it operable on batteries. When combined with our T-VSR02-15Z power supply for AC100V, it allows for extremely low-cost system construction. It can be manufactured in a short lead time and comes with a characteristic measurement report for each unit.
