*It can be easily connected with potentiometer.
*Case: waterproof, dustproof, compact and aesthetic.
*Signal output: 0~10V; 4~20mA; RS485.
*Current module: directly convert the voltage signal into 4~20mA 
current signal, divided into two-wire and three wire.
*Voltage module: Regulate 12~24V working voltage and output it into 0~10V and other voltage signal.RS485 module: convert analog signal to RS485.
