CPU connection program input device.
ACPU use. Input type: DC input, positive public end / negative public end.
Input points: 32 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/7mA.
External connection: 1 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup A953GOT-SBD Hardware A953GOT-SBD
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool. Input type: DC input, negative public end.
Input points: 16 points.
Enter the response time: 1.5ms the following A953GOT-SBD Hardware.

External connection: 3 wire.
Spring clamping terminal platform push type input module.
Input module with diagnostic function
The use of push type, do not need screw fastening, so can reduce the wiring hours.
Can be used for each 1 points to enter the wiring of the broken wire detection.
Wiring abnormality of external power supply can be confirmed A953GOT-SBD Hardware.
Using 2 pieces of structure of the terminal units, maintenance can be maintained in the same line under the condition of the replacement module. Input voltage: AC100 ~ 120V/AC200 ~ 240V.
Output voltage: DC5V.
Output current: 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. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC. Cable length: 3 meters.
For GOT and parallel printer connection. 5 slots.
Can be installed in the power supply unit for A series units installed QnA/.
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.
I/O points is an important indicator of PLC.
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 A953GOT-SBD User's Manual.
Taking into account the future adjustment and expansion,
In general should be estimaated on the total number of points plus the amount of spare 20%~30% A953GOT-SBD User's Manual.
The following describes the centralized control system I/O points of the estimate.
