For the GT1665M-STB.
Applicable model: GT16. "MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 1.5KW.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency, the device is the first power of the AC power conversion to DC (DC), the process is called rectification MR-J4-20A1-RJ
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter).
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter MR-J4-20A1-RJ. "Cable length 3M; used in A6TE2-16SRN.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.
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 MR-J4-20A1-RJ.
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 oppen contact is closed,

Provide load current and voltage MR-J4-20A1-RJ.
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 discoonnnected from the load MR-J4-20A1-RJ.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
