This TAA compliant 4-port industrial USB hub provides four USB 2.0 ports to connect your devices. The USB 2.0 hub can be surface or DIN rail mounted, providing convenient USB connectivity in a work area, server room, or industrial environment. The USB hub, with its rugged metal housing and IP30 protection rating, is built to meet the harsh demands of industrial environments. The 15kV ESD Protection (Level 4) reduces the risk of disruption caused by high static industrial environments, which can lead to costly service calls and downtime. To ensure maximum performance, the industrial USB hub provides an extended operating temperature range (-40°C - 85°C). The hub\'s wide-range 7-48V DC terminal block input gives you the flexibility to power the hub as required, based on your own power input capabilities. For low-power applications, the hub can be operated through the host USB bus power. For easy port access, the 4-port industrial USB hub can be surface or wall-mounted, and includes an optional DIN rail mount kit. The plug-and-play ports connect easily to printers, cameras, sensors and other devices. Each port also features its own Transaction Translator (TT), to assist with load balancing and ensure each port can operate at peak performance.
