A set of 5 (LOGO removable, man-machine interface provides one).
Applicable model: A985GOT (-V). For common cathode input module (3 line type).Input voltage range: DC110V.
Output voltage: DC5V.
Output current: 8A.
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 A2NCPU-S1 Programming Manual A2NCPU-S1
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% A2NCPU-S1 Programming Manual.
The following describes the centralized control system I/O points of the estimate. Output points: 16 points.
Voltage: DC24V/AC240V, 2A/1 point, 8A/1 public end.
Output type: relay output.
Response time: 12ms.
8 point /1 a public side.
20 point terminal station.
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 A2NCPU-S1 Programming Manual.
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 MITSUBISHI A2NCPU-S1 Manual .
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 MITSUBISHI A2NCPU-S1 Manual . .
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 MITSUBISHI A2NCPU-S1 Manual .
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 singlle 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 A2NCPU-S1 Programming Manual A2NCPU-S1 Dedicated Instructions.
