With the surge absorber.
Control solenoid valve required I/O points by the action principle of the solenoid valve can be known,
A single coil solenoid valve with PLC control to 2 input and 1 output,
A double coil solenoid valve requires 3 inputs and 2 outputs,
A button needs an input; a light sensitive switch needs 4 or 2 inputs,
A signal lamp needs 1 output, band switch,
Several bands are required for several inputs,
In general, a variety of position switches are required to take up 2 input points A1S62RD4 User's Manual A1S62RD4
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process A1S62RD4 User's Manual.
The number of I/O thyristor DC motor control required tube DC motor speed control system is the main form of DC speed regulation,
The thyristor rectifier unit is used to supply power to the DC motor MITSUBISHI A1S62RD4 Manual .
PLC control of the DC drive system, the input of the PLC in addition to the main signal outside the signal,
We need to consider the switching signal, the fault signal transmission device, brake signal and fan fault signal MITSUBISHI A1S62RD4 Manual .
The output of the PLC mainly consider the speed command signal positive 1~3 level, 1~3 level, allowing reverse switching signal and brake open signal etc..
In general, a reversible DC drive system controlled by PLC is approximately 12 input points and 8 output points,
An irreversible DC drive system requires 9 inputs and 6 output points MITSUBISHI A1S62RD4 Manual . 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.
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.
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 measuree of how much the user application can store the number of indicators A1S62RD4 Hardware.
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 llogical operation instructions each account for 1 words A1S62RD4 User's Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
