Bộ chuyển đổi 1 kênh tương tự sang 1 kênh xung PWM ICP DAS tSG-3781L 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-3781L 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-3781L 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
