Main functions, features and innovations of GT505K series motor intelligent monitoring device:

- support DC 110/220V or AC220V auxiliary power supply.

In the hardware system using distributed architecture design, modular, high degree of standardization, convenient installation, easy networking, convenient on-site maintenance.

- all the wiring used in all plug and plug connection drawing, using high reliability of the plug-in, eliminate the hidden danger of bad contact.

In the back insert structure, electrical completely separate, can greatly reduce the external electromagnetic interference coupling in low voltage side, enhance the ability of anti-jamming devices, improve the reliability and safety.

- equipped with overload, less power, blocking, blocking, current imbalance, phase failure, grounding, leakage, overvoltage, undervoltage, contactor breaking capacity, fast breaking, short circuit protection function.

Remote starting - Standard (self starting protector), direct starting (machine side button box full voltage starting, starting and starting) (star delta, autotransformer, frequency sensitive rheostat starting) and other starting mode, and can set the starting mode.

In the standard measurement parameter information, fault records, operation management information, convenient query failure, motor maintenance.

In the standard call self starting function and anti shake function, loss of weight, starting batch restart function.

- standard grounding protection function, the leakage protection of zero sequence current measurement of additional members.

LCD - High Definition LCD screen display menu and Chinese characters, Chinese technology is simple and easy to use, all kinds of information collected at any time display, especially suitable for on-site commissioning and maintenance.

- using industrial grade high performance microprocessor, complete protection device structure, with protection, measurement and control and alarm function.

DI/D0 - switch input and output can be freely selected programming function.

- DI support dry contact input, by means of their own supply DC24V power as a guarantee, and do not need external auxiliary power supply.

Send the output 4-20mA current - with 1 standard variable.

Standard RS-485 communication interface, ModbusRTU communication protocol.

Has the heat accumulation and heat release of memory - memory upgrade version, fill the blank of motor protector has the heat accumulation and heat release of memory and memory function.
