R4AVA07 7ch 5V 10V Analog Voltage acquisition Sampler RS485 ModBus RTU Module for PLC Oscilloscope ADC 4-20ma Sensor

1: Operating Voltage : DC 8-25V(DC 9V 12V 15V 24V)
2: Operating Current : 10-15MA
 
3: MODBUS RTU Command support 03 06 function code
 
4: 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
 
8 :Size: 45 * 30 * 15mm
9 :Weight: 10g

 

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),  Recommend to buy a new version. click here : N4AIA04
