Ver1.00，2023 Mar. ～1～tSG-3781B/tSG-3781L User ManualIntroductionThe tSG-3781B/L is a 1-channel DC current input signal conditioning module which can convert 4 ~ 20 mAcurrent input to PWM output. This provides an economical solution when the 4 to 20mA current need to beconverted to PWM output. The duty cycle, 0% to 100%, of the PWM output is a linear transformation of the 4 to20mA current input. The frequency of the PWM signal can be in the range 600Hz to 800Hz and it can beadjusted by buttons.The tSG-3781B/L includes a monochrome graphic LCD display which shows the duty cycle and frequency ofthe 1-channel PWM output signal. 4 kV ESD and 4 kV EFT protection are also provided to enhance noiseprotection capabilities in industrial environments.Note1: The setting buttons are at the bottom of the LCD. (tSG-3781B)The setting buttons are on the left side of the LCD. (tSG-3781L)Appearance
