Input and output points: 480 points.
Input / output data points: 480 points.
Program capacity: 8k.
Basic command processing speed (LD command) s:1.25.
RAM memory capacity: 32K, power supply (DC24V).
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance A3ACPUP21-S1 datasheet PDF catalog A3ACPUP21-S1 PDF datasheet.
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 A3ACPUP21-S1
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 A3ACPUP21-S1 datasheet PDF catalog A3ACPUP21-S1 PDF datasheet.
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.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words A3ACPUP21-S1 datasheet PDF catalog A3ACPUP21-S1 PDF datasheet. 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. 3C-2V/5C-2V coaxial cable.
Single bus.
Remote I/O network (remote control station).
How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps.
Design PLC peripheral hardware circuit.
Draw the electriical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc A3ACPUP21-S1 datasheet PDF catalog A3ACPUP21-S1 PDF datasheet. .
The electrical schematic diagram of the system compoosed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram A3ACPUP21-S1 datasheet PDF catalog A3ACPUP21-S1 PDF datasheet.
So far the system''s hardware electrical circuit has been determined.
