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.
