HONEYWELL 05701-A-0502 Multi-Circuit Temperature Control System

05701-A-0502 has four main aspects of the basic functions, namely, real-time control function, display function, data processing function, alarm and fault handling function [4]. According to the main functions of the above system, the overall structure of this multiplexed temperature control system is designed, and the schematic diagram of the overall system structure is shown in Figure 3. The hardware of the whole temperature measurement and control system includes data acquisition module, output control module, RTD, solid state relay, human-machine interface and total controller. The overall architecture of the system is described below from the temperature sensing and acquisition, the total controller and the actuator, respectively.

05701-A-0502 to single-zone temperature measurement, for example, each single-zone cavity set two temperature measurement points, each single-zone control point temperature measurement using two Omron’s e52-p10ae pt100 RTDs, the maximum temperature measured to meet the process requirements of the temperature control system, due to the blade mold cavity temperature measurement is not electrically conductive, so the pt100 without the need to install insulation Casing. At the same time, the use of pt100 RTD temperature measurement can effectively avoid the use of thermocouples as sensors produced by the cold end of the compensation error, improve the accuracy of temperature measurement. 4-channel input module cj1w-ad04u for temperature data acquisition.

The 05701-A-0502 serves as the master controller to coordinate the temperature control of all single loops. The plc has a cpu unit with built-in loop control function, which can directly realise multi-segment temperature and slope control. According to the functions to be achieved by the mould temperature control system, the user system requires program development for the following: animation display, compilation of control strategies, output of real-time curves, historical curves, real-time data, historical data, design of operation interface and menu, connection of external devices, operation test, etc.
