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.

PWM Duty Cycle and Frequency setting
PWM duty cycle and frequency setting show the button switch positions used to
configure the channel PWM duty cycle and frequency range. The PWM frequency
configuration button switches are located left side the module for front view.
| PWR | The power LED of the module |
|---|---|
| Mode | Press MODE to modify the channel frequency, the channel frequency |
flashes. Long press MODE to modify the four-channel frequency at the same
time, and the four-channel frequency flashes.
Up| Press UP to increase the frequency, long press to increase quickly.
Down| Press DOWN to decrease the frequency, long press to decrease quickly.
Set| Press SET to save the modified value. If only one channel is modified, it
will switch to the next channel.
If it is to modify the four channels, stop the modification.
Press MODE during the modification to stop the modification.
