The tSG-3781B/L is a single-channel DC current input signal conditioning module that converts 4~20mA current input to PWM output. PWM output has a duty cycle of 0%~100% and performs a linear conversion of the 4~20mA current input. PWM output frequency is adjustable from 600Hz to 800Hz via push buttons. tSG-3781B/L includes a monochrome LCD display that shows the duty cycle and frequency of the PWM output signal.
Note1: Setting buttons are located at bottom side. (tSG-3781B)
               Setting buttons are located at left side. (tSG-3781L)

Features:

• Convert 1-channel 4 ~ 20mA Current Input to 1-channel PWM Output
• PWM output duty ratio converted by 4 ~ 20 mA Input
• PWM output frequency configured via push buttons
• LCD displays the PWM output duty ratio and frequency

• Heating system in buildings     • Ventilation system     • Controlling servo-assisted diaphragm valve  tSG-3781L
