24 Port Industrial Network Switch

The 26 Port Unmanaged Industrial Ethernet Switch is designed for industrial network applications. It provides an easy way to access Gigabit Ethernet. This switch’s robust design makes it ideal for deployment in industrial and outdoor surveillance settings. It can optionally support DIN-Rail mounting or Wall mounting. LEDs provide visual monitoring of Ethernet-connected devices via twisted-pair RJ45 ports. The models are available in both non-PoE and PoE versions and can power the latest high-powered PoE devices over a wide industrial operating temperature range.

Ensure Industrial Network Switch Operate in Harsh Environments

24 Port Industrial Network Switch is designed for reliability and ease of maintenance. It features such as a fanless design and low power consumption. 24 Port Industrial Network Switch can operate at low and high temperatures thanks to mature technology. It is also resistant to electric interference, salt fog, vibration, and shocks. The system also features redundant dual power supplies, allowing for additional reliability for applications that require always-on connections.

Enabling Industrial Network Deployment Capacity Extension

With 24 Port Unmanaged Industrial Network Switch, The video surveillance administrators may select a transceiver based on the transmission distance and speed requirements. It is possible to extend the distance from 550 meters to 2 kilometres (multi-mode fibre) and up to 10/20/40/60/80/120 km (single-mode fibre or WDM fibre). Many enterprise data centres and distributed systems are suitable for applications

Unmanaged Industrial Network Switch for IP surveillance

AI Extend: AI extend is a common PoE switch feature designed to extend PoE distance up to 250m. The downside is that port speeds will be limited to only 10Mbps.

AI PoE: The AI PoE feature allows the switch to periodically check the ports for activity. If a port is not passing traffic for a certain amount of time, the switch will reset the power on that specific port.

NOTE: AI PoE function based on the product model.

Powerful 24 Port Unmanaged Industrial Network Switch

AI VLAN: AI VLAN is essentially port isolation on each PoE port. All PoE ports can only communicate with the uplinks when this option is enabled.

AI QoS: When AI QoS is enabled, 1-8 port prioritises video and VoIP traffic flows over others. For example, an IP camera streaming in real-time takes preference over a user transferring a backup file to a server.
