Input voltage range: AC100-120V/AC200-240V.
Output voltage: DC5/24V.
Output current: 5/0.8A.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference A1SD71-S2 User's Manual A1SD71-S2 Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC. Enter 32 points.
5mA DC24V.
Response time: 0.3ms.
32 point 1 public.
Output 32 points.
DC12/24V.
Leakage current: 0 A1SD71-S2 User's Manual. 1mA OFF.
Response time: 1ms. 32 point 1 public.
Protection function.
Surge.
40 pin connector.
Switching value, also known as logic, refers to only two values, 0 or 1, ON or OFF.
It is the most common control, it is the advantage of PLC control,
Is also the most basic application of PLC.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order A1SD71-S2 User's Manual.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic.
And the control principle is decentralized, centralized and hybrid control three. A set of 5 (LOGO removable, man-machine interface provides one).
Applicable model: A975/970GOT (-B). Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
AnNCPU command processing time and ACPU compare to 10-20% high speed processing.
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. 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 forr 2~4 A1SD71-S2 Manual.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure A1SD71-S2 Manual.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
