⇒Product introduction：

REX521GHHPSH51G is a motor protection relay manufactured by ABB, which belongs to the REX521 series. This series of relays typically have a variety of functions, including but not limited to:
Protection function: Provide all kinds of protection required by the motor, such as overload protection, short circuit protection, phase loss protection, etc.
Measurement function: can measure current, voltage, power, power factor and electric energy and other parameters.
Wave recording function: With the fault recording ability, you can record the current and voltage waveform when the fault occurs.
Communication interface: Usually equipped with RS485 and other communication interfaces, support MODBUS and other communication protocols, easy to connect with the upper computer system.
User interface: May include LCD display and navigation keyboard for easy user operation and setup

The REX521GHHPSH51G motor protection relay is a high-performance product produced by ABB, with a variety of communication interfaces and support for a variety of communication protocols. According to the product information, this relay has two independent communication ports, RS485 interface and optical fiber interface. The RS485 interface supports a variety of communication protocols, such as MODBUS, and the optical fiber interface also supports a variety of advanced protocols, which is easy to access various background systems.

Specifically, the RS485 interface of the REX521GHHPSH51G motor protection relay can be configured with a variety of serial communication parameters, including CRC check code, Modbus mode, cell address, baud rate, stop bit, data bit, frame timeout termination, and parity check. These parameters can be adjusted through the human machine interface (HMI) to suit different communication needs.

In addition, the REX521GHHPSH51G has a fault recording module that can record the fault status through a variety of trigger conditions, including rising or falling edge trigger of the protection start signal, current or voltage measurement trigger, manual trigger, communication parameter trigger, and synchronous trigger.

In terms of power quality monitoring, the REX521GHHPSH51G motor protection relay also has the measurement function of total current harmonic distortion and total voltage harmonic distortion, which can be triggered manually by HMI or through external input signals, communication parameters, preset time and date.

Overall, the REX521GHHPSH51G motor protection relays perform well in terms of communication interface and protocol support to meet the diverse needs of industrial automation and power system communication.
