A1S64TC series component is a kind of temperature controller combined with ANS series CPU.
Components with temperature measurement input and built-in PID algorithm control output,
Can be used in a variety of temperature control occasions AJ71QE71N-B2 PDF datasheet AJ71QE71N-B2
Each component controls up to 4 loops at most.
Thermocouple input or PT100 3 wire temperature sensor input.
Control output switching signal for the output of the transistor.
BW is a signal with broken line detection function. A pack of 20.
Applicable models:
AJ65SBTC - - - type remote I/O module AJ71QE71N-B2 PDF datasheet.
AJ65VBTCU - - - type remote I/O module.
AJ65VBTCU- - type remote I/O module. Temperature sensor: PT100, 4 wire system.
The A1S62RD3 and A1S62RD4 temperature sensor input modules allow the platinum resistance temperature sensing element to be directly connected to the PLC,
This component converts a signal from a temperature measuring element to a numeric value that represents a temperature measurement value,
This temperature value can be used for the control process AJ71QE71N-B2 PDF datasheet.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of.
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on.
This phenomenon is called the I/O delay time effect. 2 slots.
Can be installed in the power supply unit for A series units installed QnA/.
Cannot extend.
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 too the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point AJ71QE71N-B2 PDF catalog.
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% AJ71QE71N-B2 PDF catalog.
The following describes the centralized control system I/O points of the estimate.
