Main functions and innovation points of GT502K 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, underload, blocking, blocking, current imbalance, phase failure, grounding, leakage, undervoltage, overvoltage protection, anti shake function etc..

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.

- equipped with measuring parameter information, fault records, operation management information, convenient query failure, motor maintenance.

Restart function - configuration, and anti shake function.

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

In the large LED digital display, easy to use, 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.

D0 - switch output can be freely selected programming function.

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

Standard RS-485 communication interface, ModbusRTU communication protocol.

- heat accumulation and heat release of memory with memory function, motor protector has filled the blank of heat accumulation and heat release of memory and memory function.
