R4AVA07 7 Channel RS485 Voltage Analog Collector ADC Modbus RTU 03 06 Function Code… Ещё

Feature: 1. The A1 234 channel voltage measurement range is 05V, while the A5 67 channel voltage measurement range is 010V. 2. The drive capability of the voltage source under test must be greater than 1MA, otherwise the measurement will be inaccurate (the MCU IO voltage cannot be measured). 3. The voltage measurement accuracy is 1percent , and if the error is greater than 1percent , calibration can be performed. 4. In addition to the computer serial super port input, the MODBUS RTU command can also be input via the PLC. 5. In the MODBUS RTU command mode, up to 247 devices can be used in parallel. 6. The MODBUS RTU instruction supports the 03 06 function code. Specification: Item Type: Voltage Analog Collector Working Voltage: 824V Working Current: 1015MA Size: Approx. 45 x 30 x 15mm 1.8 x 1.2 x 0.6in.
