SG-3784M
User Manual
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.
