MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 11kw.
SLD converter rated current: 63A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Parameters can be selected by 4 different rated current and different overload rating (SLD (ultra light load) rated, LD (light load) rating, ND (general load) rating, HD (weight) AC50VG.
Type load) for selection.
You can choose the most suitable frequency converter for use; and by selecting a transducer with a SLD or LD rated level,
Be able to reduce the size of the device (compared with the FR-A700 series, to reduce the volume of equipment)
AC50VG
For applications that require high torque at low speeds, the HD rating is the most suitable AC50VG.
The controller is used to control and monitor the frequency converter through the network.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps. 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 AC50VG.
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 poinnts and types of PLC should bee 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 AC50VG.
Taking into account the future adjustment and expansion,
In general should be estimaateed on the total number of points plus the amount of spare 20%~30% AC50VG.
The following describes the centralized control system I/O points of the estimate.
