Type of input: DC source.
Input points: 16 points.
Input voltage: 12/24DC.
Input current: 3/7mA.

Common common point: 32.
Functional block diagram language is a kind of PLC programming language, which is similar to digital logic circuit.
Different function modules have different functions.
Functional module figure programming language features: functional block diagram programming language is characterized by a functional module for the unit,
Analysis and understanding of the control scheme is simple and easy: function module is to use graphical form of expression,
Intuitive, for a digital logic circuit based on the design of the staff is very easy to master the programming;
Because the function module diagram can clearly express the function relation, the programming debugging time is greatly reduced.
Analog output DC4-20mA.
8 channel analog output module.
Ans series has now launched a dedicated 8 channel D/A components,
Both voltage output and current output can be provided.
In this way, the user system to provide a higher density of D/A features,
The same method is used to maintain the same output voltage or current output MITSUBISHI A1SX80. Program memory capacity: 8k.
Input / output points: maximum 256 points
A1SX80
A scan cycle of PLC must pass through three stages: input sampling, program execution and output refresh.
PLC in the input sampling phase: first of all, in order to scan the sequence of all existing input latches in the input terminal of the state or input data read,
And write it into the corresponding input status register,
Refresh the input, then close the input port, enter the program execution stage MITSUBISHI A1SX80. Temperature sensor: PT100, 4 wire system.
The A1S62RD3 and A1S62RD4 temperature sensor input modules allow the platinum resistance temperature sensing element to be directly connected to the PLC,
This component converts a signal from a temperature measuring element to a numeric value that represents a temperature measurement value,
This temperature value can be used for the control process MITSUBISHI A1SX80.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of MITSUBISHI DC source type input module MITSUBISHI DC source type input module.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on MITSUBISHI DC source type input module.
This phenomenon is called the I/O delay time effect. 2 slots.
Installation of the power unit can not be used for AnS QnAS/ series units installed.
The popularization and application of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment.
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students.
PLC user program is designed acccording to the control system of the process control requirements,
PLC programming language through the preparation of specifications, in accordance with the actual needs of the use of the function to design A1SX80.
As long as the user caan master some kind of standard programming language,
To be able to use PLC in the control system,
To achieve a variety of automatic control functions MITSUBISHI A1SX80.
