ISOMETER® iso415R Ground Fault Monitoring Device
- Insulation monitoring device for AC and DC ungrounded systems
- Used on control circuits and main circuits
- Two response values adjustable via rotary switch or mobile app
- Measured value display via LEDs
- Modbus RTU and NFC interfaces
The new ISOMETER® iso415R is a simple and intelligent ground-fault monitor for electrical safety in control circuits and other applications. It is for ungrounded systems for compliance with NEC Article 250.21 and CE Code Rule 10-400, and meets IEC 61557-8 requirements. It combines easy operation, multiple interfaces, flexible application options and a compact design. It is the first device of Bender's new SmartDetect series and offers maximum safety in ungrounded AC, AC/DC, and DC systems.
Fast, simple operation was a central goal in the development of the new iso415R. That is why the parameters of the ISOMETER® can be set either with two rotary potentiometers, with the Bender Connect app, or with Modbus RTU communications. With the app, the iso415R can be set up before installation. In addition, a setting made once can be transferred to any number of devices. All technical information including the manual can be conveniently accessed at any time via the QR code. The measured value is displayed by LEDs. The device, which is only 18 mm (0.7”) wide, is installed by simply pushing it into place on a DIN rail.
Easy configuration via app
With the NFC function and the Bender Connect App you can easily configure the iso415R via a smartphone.
