Input voltage range: AC100-120V/200-240V.
Output voltage: DC-15/15V.
Output current: A616DAV 0.7A/1.2A, for A616DAI.
I/O slot installation.
Is the analog output unit (A616DAV, A616DAI) dedicated power supply.
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 AC30TB datasheet PDF catalog AC30TB PDF datasheet AC30TB
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% AC30TB datasheet PDF catalog AC30TB PDF datasheet.
The following describes the centralized control system I/O points of the estimate. Input and output points: 480 points.
Program capacity: 7K step.
Basic command processing speed: 4.4 ~ 5.6us.
Power supply: input DC5V output 2A DC24V/.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way AC30TB datasheet PDF catalog AC30TB PDF datasheet. Easy maintenance.
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.
User program storage capacity: it is a measure of how much the user appliication can store the number of indicators AC30TB datasheet PDF catalog AC30TB PDF datasheet.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General llogical operation instructions each account for 1 words AC30TB datasheet PDF catalog AC30TB PDF datasheet. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
