In line with the international safety standards for the safety of CPU can be controlled at the same time the general system and safety system
FX3G-422-BD
Available through IE Field CC-Link network,
Connect the safety switch and safety light curtain system used to secure CPU,
System for the construction of a general control and safety control system.
In addition, through the use of intuitive engineering software Works3 GX,
Focus on general control and safety control programming FX3G-422-BD.
Integrate security functions into the control system.
Can be used in the previous iQ-R MELSEC series module as a general control purposes,
Use on the same substrate, it can be used to construct a hybrid system with general control and safety control.
Moreover, IE Field CC-Link network can be integrated with general communication and secure communication,
Ethernet cable can also be used in secure communication,
No need to use a dedicated cable, etc FX3G-422-BD. . 8 slots.
Power supply unit.
QnA series unit installation.
High speed access.
CE logo fit.
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.
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%.
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.
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 FX3G-422-BD.
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 discoonnnected from the load FX3G-422-BD.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
