Input voltage range: AC100 ~ 120V/AC200 ~ 240V.
Output voltage: DC5/12V.
Output current: 2.3A/1.5A.
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 A3NMACA24-UL User's Manual A3NMACA24-UL
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%.
The following describes the centralized control system I/O points of the estimate A3NMACA24-UL User's Manual.
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 A3NMACA24-UL User's Manual.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action MITSUBISHI A3NMACA24-UL Manual . Extension cable.
Length: 1000mm. 10BASE5.
When communicating in the PLC network of MITSUBISHI,
There is no sense of difference and discontinuity in the network,
Can carry on the remote monitoring, modification, debugging and other work of data communication and program,
Without taking into account the level and type of network MITSUBISHI A3NMACA24-UL Manual .
MELSECNET/H and CC-Link use the way of loop communication,
Periodically automatically send and receive messages,
Does not require specialized data communication procedures,
Simple parameters can be set MITSUBISHI A3NMACA24-UL Manual .
MELSECNET/H and CC-Link are used to transmit and receive the broadcast mode,
This can be done on the network data sharing.
For the use of Ethernet, MELSECNET/H, CC-Link network,
Can set the network parameters and various functions, simple and convenient in the Developer GX software screen. RS-232:1, RS-422/485:1.
Transmission speed: 0.3 ~ 19.2kpbs.
Computer connection function.
Design PLC peripheral hardware circuit.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc..
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined.
Printer / peripheral device connection, BASIC language function.
How to choosse MITSUBISHI PLC A3NMACA24-UL .
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw thhe I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps A3NMACA24-UL User's Manual.
