The number of I/O thyristor DC motor control required tube DC motor speed control system is the main form of DC speed regulation,
The thyristor rectifier unit is used to supply power to the DC motor MR-J4-20A
PLC control of the DC drive system, the input of the PLC in addition to the main signal outside the signal,
We need to consider the switching signal, the fault signal transmission device, brake signal and fan fault signal MR-J4-20A.
The output of the PLC mainly consider the speed command signal positive 1~3 level, 1~3 level, allowing reverse switching signal and brake open signal etc..
In general, a reversible DC drive system controlled by PLC is approximately 12 input points and 8 output points,
An irreversible DC drive system requires 9 inputs and 6 output points MR-J4-20A.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian .
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process.
Control solenoid valve required I/O points by the action principle of the solenoid valve can be known,
A single coil solenoid valve with PLC control to 2 input and 1 output,
A double coil solenoid valve requires 3 inputs and 2 outputs,
A button needs an input; a light sensitive switch needs 4 or 2 inputs,
A signal lamp needs 1 output, band switch,
Several bands are required for several inputs,
In general, a variety of position switches are required to take up 2 input points.
Analog input channel number: 4CH.

Heater disconnection detection specification: there.
External wiring connection: 18 point screw terminal two.
Temperature tracking function can be monitored in real time.
Using Works3 GX in the temperature function, can be real-time tracking temperature, in the confirmation of the temperature waveform and parameter adjustment.
In addition, the temperature can be saved as a CSV file after the export, the use of a variety of purposes.
Module binding function.
Combined with the use of up to 64 sets of temperature control module for temperature control. Can be combined with the function of the following two points.
Heating function between modules.
Peak current suppression function between modules MR-J4-20A.

Temperature rising function between modules
By cooperating with the time of arrival of a number of loops, the average temperature is controlled .
Can realize the uniform temperature control, avoid partial burning control object,
Part of the phenomeenoon of thermal expansion MR-J4-20A. Can be divided into 16 groups, with its heating up to the time,
Reduce the overall system in heating up the waste of energy.
