LINETRAXX® SmartDetect RCMS425-D Four-channel residual current monitor sensitive to AC, pulsed DC, and smooth DC

Four-channel residual current monitor sensitive to AC, pulsed DC, and smooth DC Product description The LINETRAXX® SmartDetect RCMS425-D is an AC, pulsed DC, and smooth DC sensitive residual-current monitor for earthed power-supply systems. It measures residual currents between 2 mA and 70 A with direct voltage as well as alternating voltage in a frequency range from 15 Hz to 20 kHz. Corresponding measuring-current transformers (e.g. CTUB100 and CTAC series) must be connected to the residual-current inputs. Individual response values for prewarning and main alarm can be set for each channel,...

Device features Special features • Four measuring channels for AC, pulsed DC, or AC/DC sensitive measuring • Configurable frequency response • TFT display for convenient operation and configuration • Expansion/retrofit or change of functions in the event of changed monitoring requirements • Simple configuration with Bender Connect App via NFC interface • Customer-specific factory settings possible Residual current measurement • Residual current measurement device (RCM) in accordance with DIN EN 62020-1 (IEC 62020-1) • Four channels for residual current measurement • Every channel can alternatively...

Function modules The NFC interface can be used to transmit a previously configured device parameter setting directly to the device. This function is available only via the Bender Connect App. You can find this app in the Appstores for iOS and Android. In the Bender Connect app the device first needs to be made known. Then the device-specific setting options are shown so that they can be configured. When the data is transferred, feedback is given whether the parameter configuration has been successful. Parameter settings can be transmitted to the device via the Bender Connect app by holding the...

AC/DC 100...240 V DC 24 V Back-up fuse for US: 6 A RCMS425-D and all connected CTUB102-CTBCxx devices must be supplied from the same power supply. The measuring current transformers must be connected before operation. Cable lengths to the measuring current transformer: See technical data.
