Input type: DC input, negative public end.
Input points: 16 points.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/7mA A3ACPU PDF.
External connection: 2~4 line type.
Waterproof connector type.
Strong waterproof type of IP67 protection grade.
No need to stop the system can be replaced module.
Without the use of tools can be a simple connection, save time.
Terminal resistor built-in A3ACPU
Can be installed along the 6 direction.
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and the timeliness is strong A3ACPU PDF.
Software simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy to guarantee the timeliness A3ACPU PDF.
Simulation of the process of debugging, debugging mmethod can be used to segment, and the monitoring function of programmer A3ACPU Manual . Input voltage range: DC24V.
Output voltage: DC5V.
Output current: 2.5A.
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 MITSUBISHI Programming Manual.
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 MITSUBISHI Programming Manual.
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.
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 MITSUBISHI PProgramming Manual A3ACPU Programming 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 discoonnected from the load A3ACPU Manual .
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
