Room Temperature Control System Prototype Industry Based Programmable Logic Controller Zelio SR2 B121 BD

Abstract

Prototype room temperature control system based on Programmable Logic Controller industry Zellio SR2 B121 BD works based on the room temperature rises predetermined / programmed by programming the PLC, the increase in temperature of the room and the value of the temperature rise can be monitored using the LCD screen. Room temperature control industry can work from a temperature of 0 ° C to 90 ° C degrees (Ninety derarajat Celsius). Room temperature pendali equipment industry uses three components: first controller, Zelio Logic SR 121BD, second, Integrated Circuit (IC) LM35 and third, a 24 VDC power supply. This made the system utilizes the data acquisition capabilities and decision-making. Coverage temperature can be controlled in the room ranged from 0 ° C to 90 ° C samapai. Retrieval application temperature range is based on the influence of temperature not only as a noise in the world of electronics, but also the effect on the health of the world, for example in infant incubator, the results of the quality of production, for example in food, agriculture, plantation, as well as the building's security system. Prototype room temperature control system based on Programmable Logic Controller industry Zellio SR2 B121 BD consists of hardware and software. The hardware consists of a Programmable Logic Control (PLC) type of Zelio Logic SR121BD, and software on this system created using zeliosoft software version 3. This study uses Zelio Logic SR121BD as room temperature control with a prototype measuring 20 x 40 x 25 cm3. From the test results at room temperature control system prototype based on this PLC, can be determined at the time of programming in ladder Zelio soft, so the room can be controlled at a temperature of 0ºC - 90ºC.
