Descriptions


1 product introduction
M-3002 (8 way analog input acquisition module based on Modbus) is widely used in metallurgical, chemical, mechanical, fire, fire, construction, electric power, transportation and other industrial industries as a general analog quantity acquisition module. It can access 0 to 20mA, 4 to 20mA, 0 of the output of temperature, humidity, liquid level, pressure, flow, pH value and so on. Analog signals ranging from 5V to -5 to 5V, 0 to 10V, and -10 to 10V. It supports the standard Modbus RTU protocol, and has the function of communication timeout detection. It can be used in conjunction with other devices that follow the Modbus RTU protocol.
1.1 system overview
The M-3002 module is mainly composed of power supply circuit, analog input sampling circuit, isolated RS485 transceiver circuit and MCU. The high speed ARM processor is used as the control unit, and the isolated RS485 communication interface has the function of ESD, overvoltage and over current protection, which avoids the influence of the industrial field signal on the module communication interface and makes the communication stable and reliable.
