Brief: The company's researched integrated substation of model KJ101N-F2 adopts the latest embedded microcomputer technology, large-scale integrated circuit integrates CPU, flash and interface, which simplifies peripheral circuit of the instrument and improve the structural reliability. All circuits of the substation are designed on a circuit board, and lead wires of the sensor are led out from the circuit board to improve reliability.
The instrument adopts new high molecule compound material casting shell, featured with high strength and corrosion resistance. Elegant profile plus excellent technology constitute outstanding body. Horizontal and vertical view angles of the instrument are over 130 degrees which offers convenient space to users. The instrument is nice and elegant, making incomparable volume and lightweight, with a weight of 13Kg including the intrinsically safe power supply, and the total weight plus the backup battery is no more than 17Kg.
Human-centered design is carried out in accordance with loading features of the human body. Thickness of the box is as thin as possible, which facilitates carrying and hoisting and installation. Four corners of the instrument are designed as R round corner, smooth surface plus round body reinforce affinity. A comfortable wide lifting beam is installed above the instrument, like lifting a small box in hand.
The front and rear cover structure is the front and rear cover opening structure. The front cover is intrinsically safe structure, which changes the traditional four-wall surrounding mode. Cover of the instrument is integrated with the four walls. After opening the door-shaped front and rear covers, one control circuit board of the instrument is exposed that facilitates wiring and maintenance. The rear cover is explosion-proof design. Open the explosion-proof rear cover, the A.C. power supply, power-off wiring column are exposed, 10 channels of the power design are located at one power circuit board and screw off the 4 screws to disassemble for check.
ApplicationThe analog signal input port is changed into double 4 groups (8 pieces) arranged at both sides. The shell is manufactured of high molecule casting technology, nice profile, which is the smallest and lightest substation in China, with total weight (including power supply) 27Kg. The instrument is featured with low power, high reliability and convenient use, and the functions are powerful.
