The Gazelle DIN-Rail switches consist of compact and manageable industrial switches with a wide selection of port numbers, speed and media types. Gazelle S1010i-GL and Gazelle S1020i-GL series are designed for Automatic Control System (ACS) in industrial field, while Gazelle S1000i-Li and Gazelle S1020i-Li series are cost-efficient solutions designed to meet the requirements of safe city, smart transportation, and industrial data backhaul. In addition, the Gazelle S1020i-PWR-GL series and the Gazelle S1020i-PWH-GL Series provide port with standard IEEE802.3bt, IEEE802.3at, and IEEE802.1af support. All these DIN-Rail switches enable delivery of reliable, continuous, and manageable services by complying with some industrial regulations and standards, which can operate stably for a long time in harsh environments. Network redundancy and reliability are guaranteed with LACP, G.8032 ERPS (<50ms switch-over time). All these DIN- Rail switches are IP40 rated, support dual power supplies input, adopt low-power fanless cooling technology with a wide operating temperature ranging from - 40 to 75˚C, and ensure up to 35-year Mean Time Between Failures (MTBF) and a 3-year warranty. They can support wall mounting and also rack mounting. Additionally, the Gazelle S1000i series, the Gazelle S1010i-GL Series, Gazelle S1020i- PWH-GL Series and the Gazelle S1020i(-PWR)-GL Series are designed to satisfy the requirements of data transmission in areas of smart grid (IEC 61850-3, IEEE 1613), transportation (EN50121-4), energy and industrial automation.
