Product Name: 0-5V 0-10V 7ch ADC Analog Voltage Acquisition Sampler RS485 ModBus RTU Module
Package inlcuded:
1 x R4AVA07 8-25V 7 Channel Voltage analog acquisition RS485 Modbus module
Description:
1: Operating Voltage : DC 8-25V(DC 9V 12V 15V 24V)
2: Operating Current : 11-15MA
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
