What is the analog input module?

plc analog input module is a remote site analog signal acquisition device to the computer, which utilizes RS-485 bus as a data communication lines, providing analog to 485 function, can simultaneously eight analog input to the module, and by RS-485 bus transfer to the computer. Thanks to RS-485 interface as a communication interface, which can be a combination of multiple plc modules analog signal transmission more large ones, and can be dispersed in a 485 line, using the address code to distinguish, can directly access the MODBUS RTU protocol configuration software.
Analog is any value within a certain range of continuous change, with a state is antithetical to the digital representation. Typically used for analog capture and presentation of things, such as voltage and current, or frequency parameters. The analog input module is a possible acquisition of analog (such as voltage, current, thermocouple, RTD, temperature and other values) is transmitted to a computer via a smart module 485. The communication protocol uses MODBUS RTU protocol, and industrial data acquisition to achieve a unified docking program is also very convenient.

PLC Analog Input Module

plc analog input module are a kind of analog PLC Input Module of  Series PLC.  plc module is used to connect voltage and/or current sensors and RTD or thermocouple etc. It is divided into various types according to different signal types and connection modes. Its measuring precision is 16 digits with single-ended signal input. It supports hot plug. It's an intelligent module with self-diagnosis function, it can be automatically reset and restarted if operation failure appeared. It's unnecessary to set the hardware, intelligent plc will load parameters to it automatically after it being started.

From PLC product line perspective

   From PLC product line perspective, Nanda proud extension NA400 and NA200 two existing series. NA400 series PLC is mainly used in all kinds of engineering automation, especially in the petrochemical industry, coal mining, rail transportation, plc analog input output io module  water conservancy and hydropower, plc analog input modules building automation, environmental protection, municipal and other areas;  plc controllers  NA200 series PLC, mainly in the field of automation engineering with NA400 series of product applications, focusing on logic control of packaging machinery, food pharmaceutical machinery, lifting machinery, engineering machinery, textile machinery and other fields.

unnecessarily detailed analysis of the internal circuitry of the CPU

In the user view, unnecessarily detailed analysis of the internal circuitry of the CPU, but each part is working mechanism should be enough to understand. CPU CPU controller controls the work,plc analog input modules which it reads the instruction, plc communication module  the instruction interpretation and execution of instructions. However, the pace of work is controlled by the oscillation signal. Operator used for digital or logic operations, working under the command of the controller. Register to participate in operations, and store intermediate result of the operation, input output module plc  it is also working under the command of the controller.
CPU speed and memory capacity are important parameters for the PLC, which determines the operating speed of the PLC, IO, and the number of software capacity, etc., thus limiting the size of the control.

In a redundant function implementation

In NA400 series PLC products, CPU401-0501 product is its representative products, which in addition to all NA400 series PLC as providing safe and reliable operation of  china programmable logic controller the system to all intelligent I / O design and a range of security, reliability, designed for protection, plc analog input modules but also with hardware redundancy. In a redundant function implementation, analog io module to achieve a complete scan of all data exchange, redundant communication rates up to 100 Mbps, users do not need any programming work and hot standby module, you can achieve redundancy, while hot-swappable replacement module can be flexibly applied to a single chassis and dual redundant system chassis redundant systems.

In order to control the system is reliable

In order to control the system is reliable, usually Plc logic controllers installed in a protective housing of the control cabinet to prevent dust, oil, water splashing. intelligent plc  In order to ensure that its temperature is kept within the specified temperature range, install the machine should have enough ventilation space, there must be more than 30 mm spacing between the base unit and expansion unit. input output module plc If the surrounding environment over 55 degrees Celsius, to install the fan, forced ventilation.
In order to avoid electrical interference with other peripherals, programmable controller should stay away from high-voltage power lines and high voltage equipment, should leave at least 200 mm of distance between the programmable controller and high-voltage equipment and power lines as possible.
