MITSUBISHI A1SH42P-S1 PDF datasheet Input / output module datasheet PDF catalog

Special multi axis positioning controller for NSD servo system.
Coaxial data communication line function.
Program capacity: Max 60K step.
Input / output points: 1920 points.
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 A1SH42P-S1 PDF catalog.
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 A1SH42P-S1
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 A1SH42P-S1 PDF catalog. .
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. Input voltage range: AC100-120V/AC200-240V.
Output voltage: DC24V.
Output current: 1.2A additional power supply unit.
I/O points is an important indicator of PLC A1SH42P-S1 PDF catalog.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point MITSUBISHI Input / output module PDF catalog.
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30% MITSUBISHI Input / output module PDF catalog.
The following describes the centralized control system I/O points of the estimate. A set of 5 (LOGO removable, man-machine interface provides one).
Applicable model: A985GOT (-V) MITSUBISHI Input / output module PDF catalog. Enter 64 points.
Above DC7V.
Response time: 16ms.
16 pin connector.
Output 64 points.
Response time: 16ms.
32 pin connector dynamic input and output data.
PLC is introduced by the relay control technology after the development of micro processing technology,
Can be easily and reliably used for switching control.
As the analog quantity can be converted into digital quantity, the number of digital quantity is just a number of switching value,
Therefore, after the conversion of analog, PLC can also be reliable for processing control.
Because the continuous production process often has the analog quantity, the analog quantity control is sometimes called process control.
Analog quantity is not electricity, and PLC can only handle digital quantity, quantity of electricity.
All to realize the conversion between them to have the sensor, the analog quantity into a number of power.
If this power is not standard, but also through the transmitter,
The non-standard power into a standard electrical signal, such as 1-5V, 4-20mA, 0-10V, etc..
At the same time, there is also an analog input unit (A/D),
Transform these standard electrical siggnals into digital signals,
The analog output unit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal A1SH42P-S1 PDF datasheet.
So the standard telecommunication number, the conversiion between the number of operations to use a variety of computing A1SH42P-S1 PDF catalog.
This requires the resolution of the analog unit and the standard electrical signal.
