I/O slots: 2 slots.
Can you install the power module.
Outline dimension: 155*130.
There are two types of extended floor,
A power module can be inserted, and the other one is not A173UHCPU PDF.
The choice of any type of substrate depends on the total DC5V current consumption and the power supply on the CPU main substrate.
If the total demand is less than the power output, no additional power supply,
Then you can choose a more economical expansion board A173UHCPU
Both ends of the main base plate of the CPU have an expansion interface, and can be used for extending the cable connection. A pack of 10.
Applicable models:
AJ65VBTS - - - type A173UHCPU PDF.
AJ65VBTCE - - - type.
AJ65VBTCU - - - type.
AJ65ABTP - - - type.
AJ65VBCU- - type. NSD servo system.
A73CPU (P21/R21) -S3 dedicated.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowingg through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage A173UHCPU PDF A173UHCPU Manual.
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 MITSUBISHI Programming Manual .
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program MITSUBISHI Programming Manual .
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 MITSUBISHI Programming Manual .
The input and output points and types of PLC should be determined accoording to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A173UHCPU Programming 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% A173UHCPU Manual.
The following describes the centralized control system I/O points of the estimate.
