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

The iSOLATE501 provides galvanic isolation to give protection against dangerous transients. That means you can choose from a wider variety of non-certified antennas that meet the requirements for simple apparatus:

Ultra-wide Bandwidth

In addition to covering 2.4GHz/5GHz Wi-Fi frequencies and the 900MHz ISM band, the ultra-wide 150MHz to 8GHz bandwidth of the iSOLATE501 can also be used in applications involving Marine VHF, 433MHz ISM, Tetra, and full GSM frequencies, for example.

Intrinsically Safe RF Outputs

The iSOLATE501 provides galvanic isolation to protect against dangerous transients, making most standard RF outputs intrinsically safe. That means you are no longer restricted to only using certified antennas in hazardous areas; instead, you can choose from a wider variety of non-certified antennas that meet the requirements for simple apparatus, such as the Extronics iANT2xx range of high quality and rugged outdoor antennas.

Efficient Deployment

With standard SMA connectors, you can easily install your solution. Antennas with SMA connectors can be connected directly to the iSOLATE-501; we can provide accessories, including the iSOLATE-CT connector transit, for antennas with N type connections. The intrinsically safe RF outputs also mean that antennas can be hot swapped to maximise performance and minimise downtime.
