Voltage data collector

Data collector includes: bus system data collector, Internet of things data collector, Ethernet data collector, anti-interference channel isolation data collector, AD conversion data collector, DA conversion data collector, analog data collector, digital data collector, 4-20mA data collector, multiple data collector · Ethernet RJ45 data collector, switching data collector The collector, temperature signal data collector, RS232 bus data collector, RS485 bus data collector, voltage data collector, data collector support Modbus RTU or Modbus TCP communication protocol, can calibrate the accuracy through program control, program the address and baud rate.

ISO 4021 signal isolation and acquisition module can be used to measure one voltage or current signal, and also can be used to measure two current signals or the same voltage signals that can be common ground and will not interfere with each other.

1. Analog signal input

24 bit acquisition accuracy, all signal input ranges of the product have been calibrated before delivery. In use, users can also easily program and calibrate by themselves. Please refer to product selection for specific current or voltage input range. When measuring two signals, the two input selection must be the same.

2. Communication protocol

Communication interface: one standard RS-485 communication interface or one standard RS-232 communication interface, which shall be indicated during ordering and selection.

Communication protocol: support two protocols, character protocol defined by command set and Modbus RTU communication protocol. The communication protocol can be programmed to realize network communication with various brands of PLC, RTU or computer monitoring system.

Data format: 10 bits. 1 start bit, 8 data bits and 1 stop bit.

The communication address (0-255) and baud rate (300, 600, 1200, 2400, 4800, 9600, 19200, 38400bps) can be set; the maximum distance of the communication network can reach 1200 meters, which is connected by twisted shielded cable.

High anti-interference design of communication interface, ± 15kV ESD protection, communication response time less than 100ms.
