cpu module has several models

NA200plus, is a set of three 16-point type CPU module. Three models were CPUplus-1601, CPUplus-1602 and CPUplus-1601N. New plc input output modules fully meet the functional requirements of the mechanical industry users, in the case of small volume only conventional CPU 1/4, still have high-speed counting, speed pulse and other advanced features, plc module at the same time carefully for the ease of use of the service user, reflecting Nanda proud extension of the R & D team carved, excellence rigor; the high cost to the customer selection process more "conscious" of demanding to leave the choice.
, Plus fully reflects our pursuit of value for money concept. Please keep in mind, plus does not mean increasingly greater volume, price has become increasingly more expensive; but in a small volume can be increased more performance, low price better add value. We gave up minir named, because we need to have more product content, product customers can bring more imagination. Named plus, well reflect our intentions. I believe and plus mini contrast, can give our customers even more impressed.

usefulness plc modules

plc is useful for device control, device control have device start condition (input) and and control results (output), only with external switch-off input plc's input through plc logic operation to get results, then through the output terminal to control the external relays and other components to control the boot device, stop and so on.
LC sub cpu module, and expansion modules. When the terminal is not enough that you CPU module when necessary to increase the input module plc.

the role of input and output modules plc

plc input module for receiving, various parameters of the production process. put module(Start and stop input)
plc output module is used to send PLC operation after information received and completed by various control industrial field outside the machine actuators. (The result of using the output) If the digital module is the input and output signals of some switch, if it is analog module, that is an analog output signal of the.
1. A good anti-jamming capability.
2. to meet the matching requirements of various types of industrial field signals.

plc IO module de classification

Switch means only on and off (or 1 and 0) signals, analog io module two states means that changes continuously. IO commonly classified as follows: switch: by voltage level points, 220VAC, 110VAC, 24VDC, by way of sub isolation, with relay isolation and transistor isolation. Analog: divided by signal type, there is a current type (4-20mA0-20mA), voltage type (0-10V0-5V-10-10V), etc., according to the accuracy of points, there 12bit14bit16bit like. In addition to the general purpose IO, there are special IO module plc, such as thermal resistance, thermocouple, pulse and other modules. The number of points determined by IO module specification and quantity, IO module can be more or less, but the maximum number of CPU capacity can be managed by the basic configuration, namely by the maximum floor or rack slot limit.

The PLC IO module describes

Interface PLC and the electrical circuit is output through the input section (IO) completed. plc IO module integrates the PLC IO circuit, the input registers reflect the state of the input signal, output point to reflect the state of the output latch. The input module signals into the electrical signals into digital PLC system, the opposite output module. IO into digital input (DI), switching output (DO), the analog input (AI), analog output module. Modular PLC including the cpu module, I / O modules, memory, power supply modules, backplane or rack, these modules can be configured according to certain rules of combination.

Defined PLC controller

programmable logic controller initially only circuit logic control function, so named as a programmable logic controller, and later with the continuous development of these original functions have simple computer module including logic control, timing control, analog control , multi-machine communications, and many other features, the name was changed to the plc controller. PLC controller mainly refers to digital computing operation of the electronic system programmable logic controller for controlling the mechanical production process.

plc digital input output modulePLC

We know that the plc digital input output module in order to prevent interference generated by external circuit (such as voltage spikes, noise interference, etc.) caused by non-work PLC's even a damage to components, the general digital input module side are used optocoupler to cut off the internal circuit and the external circuit electrically PLC, to ensure the normal operation of the PLC. And in the input line has a RC filter circuit to prevent false signals due to the input jitter or pulse caused by external interference
