This means that the result is not only easy to use, but HELIO itself is also quick and easy to learn, thus helping to significantly reduce development costs. Highlights: - No code: HMI development without any programming - Works anywhere: future-proof and flexible thanks to true responsiveness - Usability out of the box: HELIO does the UX design for you - Live and direct: edit with real live data from the system To complement this, we offer the right hardware in the form of the C6 X1 web HMI series. With their sleek design and first-class functionality, these HMI panels set new standards in the industry.

    2. Insulation fault location system RR 5886 / RR5887

      Insulation fault location system RR 5886 / RR5887

      Precise localisation of faults during operation The fault-detection process for insulation faults can become a costly and time-consuming process in extensive industry systems. The insulation fault location system of the VARIMETER EDS family from DOLD, consisting of a test current generator RR 5886 and the insulation fault search device RR 5887, monitors and locates insulation faults in a quick and safe manner in complex, isolated AC/DC mains (IT systems). The Modbus RTU interface allows a fast connection of the devices into existing bus systems. The corresponding current transformers ND 5017 work independent of each other. They are simply connected to the input channels of the fault locating module RR 5887, which also calibrates them. Insulation fault search devices can notably be used advantageously in complex and widespread power supply systems. Even computer centres, which are operated in unearthed mains (IT system) due to availability and insensitivity to disruption, benefit from the use of an insulation fault location system. Faulty electrical circuits can be found and removed quickly before a system break down with loss of data. The information about the location of the fault are visualised directly on the RR 5887 insulation fault search device. In addition the actual fault current values can be read, localised and visualised via Modbus. The insulation fault location system allows for automatic and quick pinpointing of faulty electrical circuits, thereby increasing reliability and system availability. You will very quickly recoup the purchasing costs for the insulation fault location system thanks to reduced maintenance costs and eliminated service interruptions. Some application examples include power plants, shipbuilding, traffic engineering, industrial systems, PV systems etc.

    3. Insulation monitor RN 5893

      Insulation monitor RN 5893

      IMD with UL 2231 approval - especially for DC charging stations Electrical safety must be guaranteed during the charging process. For this purpose, an unearthed DC power supply system (IT system) with insulation monitoring is set up and monitored with an insulation monitoring device (IMD). Dold has developed a smart insulation monitoring solution for DC charging stations that also fulfils the requirements of UL 2231. The insulation monitor RN 5893 from the VARIMETER IMD family monitors the charging process from the charging station to the vehicle in combination with the coupling device RP 5898. - Response delay < 10 s - Nominal voltage up to DC 1000 V - Manipulation protection due to sealable transparent cover

    4. Insulation monitor RN 5897/010

      Insulation monitor RN 5897/010

      Insulation monitoring for modern IT systems The demand for the availability of machines and apparatus in the region of factory machinery and process technology is constantly increasing. The requirement for this is a functioning and reliable power supply. Unexpected insulation faults in the system can lead to unwanted power supply failures, and even cause personal injury or property damage. This is why insulation monitoring equipment is typically used in IT systems. The insulation monitor RN 5897/010 from the VARIMETER IMD series by DOLD was developed especially for use with modern power supplies. These are often comprised of converters, thyristor regulators, and direct current components. Through EMV interference suppression measures, high leakage capacitance onto the ground is present. The RN 5897/010 is suited for system leakage capacitances of up to 1000 μF, and for voltages up to AC/DC 230 V. Using the additional ballast unit RR 5898, it is possible to install the unit in systems with voltages of up to AC 1000 V and DC 1500 V. Besides an adjustable alarm threshold, the insulation monitor also has an adjustable pre-alarm threshold. A multicoloured LCD screen constantly updates stating the current insulation value. The insulation monitors guarantee additional surveillance over current-free networks. A selective earth fault detection of L+ and L- enables quick fault localisation.

    5. Insulation monitor RN 5897/020

      Insulation monitor RN 5897/020

      Insulation monitoring for DC charging stations The number of electric vehicles is constantly increasing and will grow even faster in the future. This will also drive forward the expansion of the charging station infrastructure, as DC charging stations are the first choice when electric vehicles need to be charged in the shortest possible time. Electrical safety must be guaranteed during the charging process. For this purpose, an unearthed DC power supply system (IT-grid) with insulation monitoring is set up and monitored by means of an insulation monitoring device (IMD). The user must never be exposed to high voltages (up to 1000 V) at any time. The insulation monitor RN 5897/020 of the VARIMETER IMD family is used especially for DC charging stations according to the IEC/EN 61851-23:2014/AC:2016-06 standard and monitors the charging process from the charging station into the vehicle. The device is characterised by the short response delay of ≤ 1s, a rated voltage up to DC 1000 V with coupling device and the detection of asymmetrical as well as symmetrical insulation faults. The integrated voltage measurement ensures reliable detection of the insulation resistance in the IT grid. The insulation monitor also features a selftest. This takes place automatically after power-on and after every full operating hour.

    6. Insulation monitor RN 5897/300

      Insulation monitor RN 5897/300

      Safety for mobile generators The insulation monitor RN 5897/300 from the VARIMETER IMD series by DOLD was developed especially for use with mobile generators. In mobile applications, such as in emergency vehicles or on construction sites, electrical energy must be used to reliably prevent injuries and property damage. Furthermore, mobile generators need to guarantee immediate operational readiness, without requiring time-consuming procedures to set up safeguards (such as installing and calibrating grounding systems etc.). That’s why the safeguard “electrical separation with insulation monitoring and shutdown” is available. It triggers an automated shutdown within < 1 s if the insulation resistance sinks below 100 Ω / V. The RN 5897/300 meets these demands, and fulfills the requirements of DIN VDE 0100-551 for mobile generators. The insulation monitor is suitable for system leakage capacitance of up to 30 μF, and is designed for universal use in ungrounded AC, DC and AC/DC networks. Besides an adjustable alarm threshold, the insulation monitor also has an adjustable pre-alarm threshold. A multicolored LED status light keeps users informed continuously on the current operating status. The device enables reliable monitoring, even in a network without current.
