1-channel 4 ~ 20 mA Current Input / PWM Output Signal Conditioner
Features
The tSG-3781B 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 includes a monochrome LCD display that shows the duty cycle and frequency of the PWM output signal.
