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
