SFD-860The type of SFD-860 series alarm controller
High degree of intensification, flexible assembly methods. Each liquid crystal can be realistic four channel detector working state, with a small size, intuitive and clear, easy to operate, the advantages of high accuracy.
Multifunction, high cost. The alarm controller can receive the 4-20mA standard signal or the RS485 bus signal respectively. Each wire alarm can output a set of passive, a normally opened switch signal and RS485 bus signal. Can replace the PLC (programmable logic controller) to use,effectively reduce the user's equipment procurement and construction costs.
Alarm controller and detector using the bus connection, bus connection mode has both advantages of material saving and labor, time and cost, and technical advantages of numerical multiple real-time display concentration detector.
Alarm display clear, according to the working state of the equipment changes the background color. Green, pink, red, yellow four colors represent the norm, low alarm, high alarm, fault.

Optional features: can be reference to my company to provide HUAWEI product options, intelligent control software installation. After installing software, alarm device can intelligent judge whether access and pick out the equipment fault, and using fuzzy control technology, unique association is control equipment (such as fan, solenoid valve, etc.) the maximum service life. If you want to add the intelligent control software, the user should be declared in advance.
