Bộ chuyển đổi 4 kênh tương tự sang 4 kênh xung PWM ICP DAS SG-3784M CR

Feature

  • 4-channel 4 ~ 20mA Current Input to 4-channel PWM Output
  • Accuracy: ±0.1% of Full Range
  • Easy PWM Frequency configuration
  • 4kV ESD and EFT Protection
  • 2.7-inch LCD simultaneously displays PWM signal duty ratio and frequency
  • 4-button easy configuration of PWM signal

Introduction

The SG-3784M is a 4-channel DC current input signal conditioning module which can convert  4 ~ 20 mA current input to PWM output. This provides an economical solution when the 4 to 20mA current need to be converted to PWM output. The duty cycle, 0% to 100%, of the PWM output is a linear transformation of the 4 to 20mA current input.  The frequency of the PWM signal can be in the range 600Hz to 800Hz and it can be adjusted by buttons. 
The SG-3784M includes a monochrome graphic LCD display which shows the duty cycle and frequency of the 4-channel PWM output signals. 4 kV ESD and 4 kV EFT protection are also provided to enhance noise protection capabilities in industrial environments.

Application

  • Heating system in buildings
  • Ventilation system
  • Controlling servo-assisted diaphragm valve
