Programmable controller in low-voltage electrical system of dust

Level start ash, regular time 4. DC power to stop ash. Programmable controller I / o modules and a variety of testing back to 3. Automatic control of the road outside the heater DC24V power supply, display board needs +5 V power control device under temperature limit of the temperature on the components sent by the source. Signal for automatic control of electric heater. When the temperature is below the lower limit, start the heater, the temperature rose to the upper limit, stop plus four, the main function of the system heat. Temperature element 403 form, xu a 200, inspection apparatus. The system is used to complete the automatic low pressure system ESP 4. Control control other devices, to the electrostatic precipitator to create conditions for optimum operation. Also based on user requirements of fans, electric valves and high 1. Vibration pressure automatic control device to control power supply rectifier. Can be divided into continuous vibration and vibration time. Vibration time by 5. Control user requirements vibration time and stop time, and users can be divided into automatic mode and manual mode. Automatic mode to the special requirements to the design process. Is controlled by the programmable controller, according to pre-programmed 2. Discharging automatic control work. Manually in order to place or send commissioning test required by the user Ash body with interlocked. Ash Methods with the use of unusual circumstances. Can be divided into regular mode and level of ash ash way. Regular row 6. Fault detection and alarm sound and light gray by: ash is a time to start the motor, then the device can be timed to enter the system according to the feedback signal and control to stop ash; material level ash by: ash on the material level starts, the next material information in fault detection, the indicator light flashes when the device is that 25 * there is failure, the device automatically sound and light alarms; the device provides a fault alarm to lift key, press the button, clear sound the alarm, and lighting alarm is still displayed. 7. Key features of the device to provide a \02 on the display board designed to modify key parameters of time, depending on the device number, to modify the motor start and stop time. Can also be set depending on the circumstances of other keys. 8. Serial communication function of a programmable controller with an RS 232C serial communication port, the port can be connected through the host computer system, the host computer can be read through the interface input and output of the device status monitoring information. V. Conclusion practice shows, the use of a programmable controller,[link widoczny dla zalogowanych], which greatly improve the reliability of the system, the failure rate greatly reduced the maintenance operations to the scene to bring great convenience. I have used a dozen different types of PLC products, produced more than a thousand sets of ESP application of low-voltage equipment at home and abroad steel, mining, cement, petroleum, chemical, power, paper and other industries, made a good economic and social benefits.

Principle and Application of programmable controllers and application of integrated wiring system, Dalian Institute of Electronics, Qing-Pan Anbin Abstract This paper describes a PDS (integrated wiring system) the composition, and in telephone, computer network, monitoring system. Keywords PDS I. Introduction In the past the building connected with the language and data lines, you may need to use a variety of cables, wiring sockets, and joints. For example: the user switch (PBX) typically use twisted pair,[link widoczny dla zalogowanych], computer systems,[link widoczny dla zalogowanych], sometimes using coaxial cable, and local area network () you may use twisted pair or coaxial cable, these different devices using different material composition of the network; the same time , connecting these different wiring plugs, connectors, sockets and patch panels (BIoCK) are not compatible, as long as the changes in the terminal / telephone location, you must re-laying new cables and install new outlet, while construction, office operations will be interrupted and the system will not be used. In such a conventional wiring configuration, a re-planning of office space and the replacement of computer system or switch would be a money and time-consuming work. Now, a new wiring system of a PDS cabling system,[link widoczny dla zalogowanych], has been widely used among the various buildings, it will all voice, data, video and monitoring equipment, combined in a standard wiring cabling system, and will terminal connector into the various devices in a standard wall outlet. When the terminal / telephone needs a change in position, simply pull out the plug and then insert it into the new location of the outlet, and then make some simple jumper, the work is complete, do not need to put a new cloth cable and install a new outlet. When using the PDS integrated wiring system, the computer system,[link widoczny dla zalogowanych], with 26 *
