Analog input module is a device used to collect analog signal from remote field to computer. It uses RS-485 bus as a data communication line to provide analog to 485 function, which can simultaneously input analog to the module and transmit it to the computer through the RS-485 bus. This kind of module usually uses RS-485 interface as the communication interface, can combine multiple modules to transmit more analog signals, and can be distributed on the 485 line, using the address code to distinguish, can directly access the MODBUS RTU protocol configuration software.
In terms of function, the analog input module can collect standard current and voltage signals, including 0-20mA, 4-20mA two kinds of signals, and +/-2.5V, +... Equivoltage signal.
The advantages of analog input module mainly include:
Strong flexibility: The analog input module is suitable for a variety of application scenarios and can meet the needs of different users.
High precision: The analog input module has high precision and high resolution, enabling accurate data acquisition and measurement.
Good stability: analog input module adopts stable circuit design and high-quality components, which can work normally in harsh working environment.
Versatility: Analog input modules usually have a variety of functions, such as signal amplification, filtering, shaping, counting, etc., which can meet the needs of different application scenarios.
Easy integration: Analog input modules usually have standard interfaces and protocols, which can be easily integrated with other devices or systems to achieve automated control and measurement.
However, the analog input module also has some disadvantages:
Susceptible to interference: Analog input modules are susceptible to electromagnetic interference, which affects the accuracy of data acquisition.
Limited transmission distance: The transmission distance of analog input modules is usually short, and additional signal amplification and compensation are required if long-distance transmission is required.
Higher price: The price of analog input modules is usually higher, which can increase the cost of the entire system.
Maintenance inconvenience: If the analog input module fails, it needs to be replaced or repaired, which may affect the normal operation of the entire system.
