Topect touch-type temperature and humidity controller is specially developed by Topect for the industry of environmental equipment; it consists of touch screen, PLC, temperature module and humidity module, powerful in functions. The touch screen is equipped with visual editing software, PLC logic programme, extensible I&O port and extensible multi-point temperature; USB interface allows users to export data (time optional). Remote monitoring is realized through RS485 communication and PC connection.
The controllers are developed independently by our company with high performance. Characterized by 65536 color 7’’, TFT true-color touch screen and 800×480 dot matrix, it ensures realistic effects and comfortable operation. In addition, the entire interface is concise and clear, convenient and reliable.
Our controllers have powerful debugging protection function, fault alarm and troubleshooting description; extensible I&O port can be used to prepare different control programs according to requirement to realize different functions; they can be developed separately according to actual environment but can be controlled by computer intensively through software. The controller interface adopts consistent style, convenient for users’ operation.
With PLC program control, this system has timed running & stop function and power failure protection function as well as better stability.It can be connected to a centralized monitoring software and supports communication protocol, convenient for users’ secondary development; multiple test chambers can be monitored remotely.
