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

Function output module

Programmable Output Module connected to the bus loop controller can be installed in the vicinity of the control device can also be installed in the floor inside the terminal module. Electronic writing code, you can live encoding. analog output module output control logic can be completed according to project conditions Ji programming. When the controller receives the alarm signal to the detector, based on pre-programmed into the program, the controller by bus linkage control signal to the output module, the output module startup requires the linkage of fire-fighting equipment; equipment operation after receiving a signal will be answered.

Programmable Controllers and IO Modules What are the similarities and different

programmable logic controller, ie PLC, can be considered a microcontroller or CPU + interface circuitry. Under normal circumstances, the microcontroller, CPU, including the IO module plc are just low-level output signal of a weak signal, you want to direct drive packed load is generally not possible, because their output current is too small, but because the PLC plus the interface circuit, you can put a weak signal amplification signal can directly drive high current take-load, general load current can be achieved PLC 1A.

plc What is the role of the power module

plc generally have small internal switching power supply, the output voltage is used for their own chips, components and external sensor power supply module , a large current can also give small executive power components, such as solenoid valve relays, etc.
plc cpu host power supply is limited, if you add the expansion unit, or peripheral unit. When using host power beyond its rated value, then you need the power module.

Input Output Module works

plc digital output (hereinafter referred to as modules), for switching bus system fire radio systems and fire radio broadcasts normally between. Output module is embedded microprocessor, microprocessor and fire alarm controller communications, power bus brownout detect, input and output line fault detection, output control, digital input module signal logic state judge, the status indicator control. Module after receiving the fire alarm control start command, pull the relay, the scene shifted from the normal speakers to fire radio broadcasts, and light indicator, while the answer signal information to the fire alarm controller, indicating that the switch was successful

Modules include what kinds of

 plc module should include IO modules (analog and digital input and output modules), cpu module, communications module, the general PLC does not require power modules, such as S7-200, while others require a power supply module PLC, such as S7-300 . According to the actual needs of the PLC module combination, such as CPU + DIC) + AI (analog input) + DO (digital output) + AO (analog output) + CP (communication module), if necessary, together with the PS (power supply module) basically able to achieve the desired purpose.

plc IO module

Interface PLC and the electrical circuit is output through the input section (I / O) to complete. plc IO module integrates the PLC's I / O circuit, the input register reflecting the input signal, the output point to reflect the state of the output latch. Input module into the electric signal into a digital signal the PLC system, the opposite output module. I / O into the digital input (DI), switching plc analog input output module, the analog input (AI), analog output (AO) modules.

Programmable Logic Controller (PLC) hardware measures:

The main modules are used large-scale or large scale integrated circuits, a large number of switching operations performed by non-contact electronic memory, plc IO module system design have improved the channel protection and signal conditioning circuit.
① shield - to power transformers, CPU, programmers and other major components, the use of electrical conductivity, magnetic shielding material good, to prevent outside interference.
② filter - the power supply system and an input line filter in various forms, such as intelligent plc or π-type filter network to eliminate or suppress high frequency interference, but also weakened the interaction between the various modules.
③ power adjustment and protection - the core components of the microprocessor needed a + 5V supply, the use of multi-stage filter and make adjustments with the integrated voltage regulator to adapt to fluctuations in the exchange and over-grid voltage, under influence of voltage.
④ isolation - between the microprocessor and I / O circuits, opto-isolated, effectively isolate the electrical connection between the I / O interface with the CPU contact, reducing failures and malfunctions; between the I / O port also isolated from each other.
⑤ with modular structure - This structure helps in case of failure to repair short. Once identified a faulty module can easily be replaced quickly, allowing the system to resume normal work; also helps to accelerate find the cause of the fault.
