SG-3784M - 4-channel current converter 4 ~ 20 mA to 4 channels of PWM signal

15 June 2023 Product News

ICP DAS has presented a new 4 ~ 20mA DC to PWM output signal converter. SG-3784M is a 4-channel converter of input current 4 ~ 20 mA to PWM signal output. This is an economical solution when only 4 to 20mA current needs to be converted into a PWM output signal. The duty cycle from 0% to 100% of the PWM output is a linear conversion of the 4 to 20 mA input current. The PWM signal frequency can range from 600Hz to 800Hz and can be adjusted using the buttons.

SG-3784M has a monochrome LCD graphic display that shows the duty cycle and frequency of the 4-channel PWM outputs. 4 kV ESD protection is also included to enhance noise protection capabilities in industrial environments.

The device can be used in systems such as:

  • Heating system in buildings
  • Ventilation system
  • Actuated diaphragm valve control
