tSG-3781B/tSG-3781L User Manual
Introduction
The tSG-3781B/L is a 1-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 tSG-3781B/L includes a monochrome graphic LCD display which shows the duty cycle and frequency of
the 1-channel PWM output signal. 4 kV ESD and 4 kV EFT protection are also provided to enhance noise
protection 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)
