Main features and innovations of GT505K series motor intelligent monitoring device:
■ The auxiliary power supply supports DC 110/220V or AC220V.
■ The hardware system adopts distributed structure design, modularization, high degree of standardization, easy installation, easy networking, and easy on-site maintenance.
■ All wires are connected by plug-and-pull plugs, and plug-ins with high reliability are used to completely eliminate the hidden danger of poor contact.
■ Adopt back-plug structure, the strong and weak electricity are completely separated, which can greatly reduce the coupling of external electromagnetic interference on the weak electricity side, enhance the anti-interference ability of the device, and improve its reliability and safety.
■ Equipped with protection functions such as overload, under power, locked rotor, blockage, current imbalance, open phase, grounding, leakage, under voltage, over voltage, contactor breaking capacity, quick break, short circuit and so on.
■ The standard is equipped with multiple starting methods such as remote signal start (the protector starts by itself), direct start (full-voltage start by the button box next to the machine), forward and reverse starting and step-down starting (star-delta, autotransformer, frequency-sensitive rheostat start), etc. , And the starting mode can be set on site.
■ Standard configuration of measurement parameter information, fault record, operation management information, convenient to query the cause of the fault, and perform motor maintenance.
■ comes standard with self-starting function, as well as anti-shake function, loss-of-voltage restart, and batch restart functions.
■ The standard grounding protection function can be added to the leakage protection function of zero-sequence current measurement.
■ High-definition LCD screen and Chinese characters display, easy-to-use Chinese menu technology, all kinds of collected information can be displayed at any time, especially suitable for on-site debugging and maintenance.
■ Adopt industrial-grade microprocessor, constitute a high-performance complete set of protection and control device, with protection, measurement, control and alarm functions.
■ DI/D0 switch input and output can freely select the programmed function.
■ DI supports dry contact input, which is guaranteed by the device's own supply of DC24V power, without the need for external auxiliary power.
■ Equipped with 1 standard 4-20mA current transmitting output.
■ Standard RS-485 communication interface, ModbusRTU communication protocol.
■ The enhanced version has thermal accumulation memory and thermal release memory functions, which fills the gap that the motor protector has thermal accumulation memory and heat release memory functions
