1.:Only 0-20ma Output


  • Model Number 4 to 20ma signal generator Power supply DC 15V to 28V Power consumption Less 2W
  • Output current range 0mA to 22mA adjust (default 0-20/4-20mA) Output adjustment accuracy 0.1mA, error <0.05mA
  • Load sampling resistance <500 ohm Working Temperature 0-40C,RH<80%
  • Press and hold the knob for 2 seconds to enter the parameter setting, the parameter number "FO1" is displayed, when the parameter number is displayed, rotate the knob "+" and "-" to modify the parameter number, then press the knob to modify the parameter value, and press the knob again to save and exit ;
  • Adopt standard MODBUS-RTU message format, slave mode address 1-127 (factory setting 1), baud rate 2400-57600 (factory setting 9600), no parity; There is no 1209 terminal resistance inside. When the bus speed is far away and there are many devices, the user needs to connect the terminal resistance to make the transmission more stable; the use of high-quality shielded twisted pair can increase the anti-interference ability of communication; MODBUS-RTU message format , commands and examples:
