Description
Description:1: Operating Voltage : DC 8-25V(DC 9V 12V 15V 24V)2: Operating Current : 10-15MA3: MODBUS RTU Command support 03 06 function code4: The A1/2/3/4 channel voltage measurement range is 0-5V, and the A5/6/7 channel voltage measurement range is 0-10V. The drive capability of the tested voltage source must be greater than 1MA, otherwise the measurement cannot be accurate (MCU IO voltage cannot be measuring)5: Voltage measurement accuracy of 1%, calibration can be calibrated if the error is greater than 1%6 :MODBUS commands can be made serial HyperTerminal (serial assistant) OR PLC Enter;7 :Under the MODBUS command mode, it can support up to 247 devices in parallel
