Input voltage range: AC100-120V/AC200-240V.
Output voltage: DC5V.
Output current: 8A.
For Q4ARCPU.
The control module monitors the power supply, the error
CPU state,
And its own error state.
It sends out
Error signal a6raf and open the corresponding
Relay output.
I/O points is an important indicator of PLC A970GOT-TBD-B datasheet PDF catalog A970GOT-TBD-B PDF datasheet.
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 A970GOT-TBD-B
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% A970GOT-TBD-B datasheet PDF catalog A970GOT-TBD-B PDF datasheet.
The following describes the centralized control system I/O points of the estimate. Input voltage range: AC100 ~ 120V.
Output voltage: DC24V.
Output current: 0.6A.
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 A970GOT-TBD-B datasheet PDF catalog A970GOT-TBD-B PDF datasheet.
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.
