With the LINETRAXX® SmartDetect RCMS425, Bender now offers two new residual current monitoring devices for earthed power supply systems. The devices were developed in accordance with the DIN EN 62020-1 standard, can monitor four channels simultaneously and have a Modbus RTU interface for easy connection to the higher-level control technology. The devices can be parameterised with the Bender Connect app via the existing NFC interface.
本德尔现在推出了两款专为接地电源系统设计的新款剩余电流监视仪 - LINETRAXX®SmartDetect RCMS425。新产品是根据DIN EN 62020-1标准研发，能够同时监控四个通道，并配备Modbus RTU接口，便于与高级控制技术连接。用户可通过Bender Connect应用程序，利用现有的NFC接口对这些设备进行参数设置。
Both LINETRAXX® SmartDetect RCMS425-L and LINETRAXX® SmartDetect RCMS425-D are equipped with state-of-the-art measurement technology and are suitable for use in earthed power supply systems. The devices measure AC, pulsed and DC residual currents in a frequency range up to 20 kHz. The measuring range extends from 2 mA to 70 A, the response values for residual currents of type A/F from 6 mA to 30 A and for residual currents of type B/B+ from 10 mA to 10 A.
LINETRAXX ®SmartDetect RCMS425-L和LINETRAXX ®SmartDetect RCMS425-D均配备了最先进的测量技术，适用于接地供电系统。新款剩余电流监视仪能够测量频率高达20 kHz的交流、脉冲和直流剩余电流。测量范围从2 mA到70 A； A/F型剩余电流，响应范围为6 mA至30 A； B/B+型剩余电流，响应范围为10 mA至10 A。
Separately adjustable response values allow a distinction to be made between pre-warning and main alarm as well as between RMS value, the individual AC and the individual DC component. With the help of special analysis functions, harmonics up to the 400th harmonic can be detected.
通过独立可调的响应值，可以区分预报警和主报警，以及RMS值、各交流分量和各直流分量。借助特殊分析功能，可检测高达400次谐波。
In addition to the four residual current inputs, the RCMS425 has a further digital input, a digital input and output (IO) and a multifunctional digital/analogue output. Two alarm relays for pre-warning and main alarm round off the interfaces.
除了四个剩余电流输入端口外，RCMS425还额外有一个数字输入、一个数字输入输出(IO)以及一个多功数字/模拟输出。两个报警继电器分别用于预报警和主报警，完善了系统接口功能。
The RCMS425 can be easily integrated into new and existing electrical systems via the existing Modbus RTU interface. The parameters required for electrical systems are set either via Modbus RTU or using the NFC interface via the Bender Connect app. Settings can also be made via the Bender Connect app when the power is switched off.
RCMS425可以通过现有的Modbus RTU接口轻松集成到新的或者旧的电气系统中。电气系统所需的参数可以通过Modbus RTU或Bender Connect应用程序的NFC接口进行设置。当电源关闭时，也可以通过Bender Connect应用程序进行设置。
The RCMS425 is available in two versions. With the RCMS425-L, several coloured LEDs indicate the current status of the system. The RCMS425-D has a colour LCD display that provides more information and therefore an even quicker overview.
RCMS425提供两种版本。RCMS425-L配备多个彩色LED灯，显示系统当前状态。RCMS425-D则采用彩色LCD显示屏，提供更多信息，从而实现更快捷的浏览。
Both versions can be operated with an operating voltage of AC/DC 100...240 V or DC 24 V via the built-in wide-range power supply unit, so that no external power supply is required. Alternatively, operation with DC 24 V via an external power supply unit is also possible. The functionality can be extended via function modules, e.g. for harmonic analysis and for connecting measuring current transformers from other manufacturers.
两个版本均可通过内置的宽范围电源模块，以交/直流100...240V或直流24V的电压运行，因此无需外部电源。此外，也可以通过外部电源模块以直流24V运行。功能可以通过功能模块扩展，例如用于谐波分析和连接其他制造商的测量电流互感器。
Both variants are only 36 mm wide (2 HP).
