iSOLATE501 Ultra-wide band RF isolator

The iSOLATE501 is an ATEX and IECEx approved RF galvanic isolator for use in Zones 0, 1, 2, 22, and mining applications. It is the next generation of Extronics’ ground-breaking RF isolation technology, designed to improve further on the performance of the industry-proven iSOLATE500.

The iSOLATE501’s galvanic isolation protects against dangerous transients being transmitted through to the antenna, making the majority of standard RF outputs intrinsically safe. This means that you can use non-certified antennas within hazardous areas, as long as they meet the simple apparatus requirements laid out in the installation standards. The Extronics iANT2xx range of high quality and rugged outdoor antennas have all been assessed by our team of engineers to ensure they meet these requirements.

    • Intrinsically safe
    • High performance over ultra-wide bandwidth
    • Compact design

    Highly compact

    Thanks to its unique design, the iSOLATE501 is small and lightweight; a practical solution for a number of different applications.

    Efficient deployment

    Quickly install your solution; antennas with an SMA connector can be connected directly to the iSOLATE501. We can also provide accessories such as junction boxes and couplers to enable N-type connection, as well as DIN rail mounting clips. Antennas can also be hot-swapped, giving greater flexibility and ROI.

    Ultra-wide bandwidth

    The innovative iSOLATE501 gives exceptional performance over an ultra-wide frequency band of 150 MHz to 8 GHz, with minimal losses.

    Maximise performance

    Intrinsically safe, galvanically isolated outputs enable the use of non-certified antennas, such as the Extronics iANT2xx range of high quality, rugged, outdoor antennas, giving you a wider choice to best suit the application without costly and time-consuming assessment by notified bodies.
