Input and output points: 480 points.
Program capacity: 7K step.
Basic command processing speed: 4.4 ~ 5.6us.
Power supply: input DAC100 ~ 120/200 ~ 240V/ output 2A DC24V, 0.5A DC5V.
Optical data communication line.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way . Easy maintenance.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage MR-J3BUS40M-B
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load MR-J3BUS40M-B.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
User program storage capacity: it is a measure of how much the user application can store the number of indicators MR-J3BUS40M-B.
Usually in words or K words as units . 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. 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.
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.
The response time of PLC is the interval between the time of the change of the external output siignal 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 usse oof the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on MR-J3BUS40M-B MR-J3BUS40M-B.
This phenomenon is called the I/O delay time effect.
