Bộ chuyển đổi 1 kênh tương tự sang 1 kênh xung PWM ICP DAS tSG-3781B CR
Feature
- Convert 1-channel 4 ~ 20mA Current Input to 1-channel PWM Output
- PWM output duty ratio converted by 4 ~ 20 mA Input
- PWM output frequency configured via push buttons
- LCD displays the PWM output duty ratio and frequency
Introduction
The tSG-3781B is a single-channel DC current input signal conditioning module that converts 4~20mA current input to PWM output. PWM output has a duty cycle of 0%~100% and performs a linear conversion of the 4~20mA current input. PWM output frequency is adjustable from 600Hz to 800Hz via push buttons. tSG-3781B includes a monochrome LCD display that shows the duty cycle and frequency of the PWM output signal.
Application
- Heating system in buildings
- Ventilation system
- Controlling servo-assisted diaphragm valve
