Optional features of memory card (A/FX compatible).
2MB extended memory.
Applicable models: A985 (-V) /975/970/A960GOT (-B) /A956WGOT. Input and output points: 480 points A975GOT-TBD PDF.
Program capacity: 7K step.
Basic command processing speed: 4.4 ~ 5.6us.
Power supply: input DAC100 ~ 120/200 ~ 240V/ output 2A DC24V, 0.5A DC5V.
Coaxial data communication line function.
Modular: PLC is the basic components of a separate module A975GOT-TBD
Medium and large PLC used this way. 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 thhe normally open contact is closed,
Provide load current and voltage A975GOT-TBD PDF A975GOT-TBD 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 disconnected from the load A975GOT-TBD PDF.
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 application can store the number of indicators MITSUBISHI User's Manual.
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 logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4 MITSUBISHI User's Manual. Multi axis positioning controller.
Coaxial data communication line function.
Program capacity: Max 60K step.
Input / output points: 1920 points.
PLC commonly used in memory are EPRROM, EEPROM and with lithium battery powered RAM A975GOT-TBD User's Manual.
General micro and small PLC storage capacity is fixed, between 1~2KB MITSUBISHI User's Manual.
How much memory is occupied by a user application is related to many factors,
Such aas I/O points, control requirements, computing processing, program structure, etc A975GOT-TBD Manual. .
So it can only be roughly estimated before the program is designed.
