BRN-M401, BRN-M403 motor protection devices

BRN-M401, BRN-M403 motor protection device series intelligent motor protection and control device is mainly used in low voltage 690V motor control systems, motor overload, short circuit, over long time to start, stall, uneven ground, undervoltage, Hazard overvoltage, process interlock failure are to be protected, and a comprehensive set of three-phase power measurement / display, digital input / output and network communication in one. Each unit has a variety of integrated power parameter measurement function, can be used alone as an electrical measuring instruments, it may be used as the front-end integrated automation control system of power, enabling measurement, monitoring, protection, control and other integrated functions, through its standard RS -485 communication interface and twisted pair network communication and monitoring systems, easy remote management of data and the "four remote" function. Series intelligent motor protection and control devices are designed for low voltage motor control systems, ultra-small dimensions, suitable for GCK, GCS, GGD, MNS and other out of style (including 1/4 drawer), fixed and hybrid cabinet type installation. With easy installation, reasonable layout, easy maintenance, saving cable, safe and reliable, and other advantages; fully embedded SOC (System On Chip SoC) design, 32-bit DSP (Digital Signal Processing Digital signal processing technology and redundancy fieldbus technology, optimized full-wave AC sampling FFT (Fast Fourier Transform Fast Fourier Transform) technology, software is modular, high anti-jamming design; means power, communications, and the machine running, the alarm has LED indication, easy inspection, maintenance system ; binary input with up to 8-way acquisition, and four out of the amount of control; with short circuit protection, definite time, inverse time protection, stall, start time long, unbalanced, over-voltage protection and other protection capabilities, comprehensive security operation to protect the motor; can be networked with SIEMENS, SCHNEIDER, GE, AB, and other brands of PLC; while networking software and KINGVIEW, FIX, WinCC, Intouch, etc; with separable, miniaturization Chinese LCD operator / display terminals, can directly monitor equipment operating status, operating parameters, and modify the protection settings and parameters
