According to Switchtech, its Ethernet switches are available in 5, 8, and 16 port variants, and are unmanaged types, meaning they require no setting up.
An unmanaged switch, Switchtech explains, allows Ethernet devices to communicate with each other automatically using auto-negotiation to determine parameters such as data rates and whether to use half-duplex or full-duplex mode.
Kyland’s Opal series Ethernet switches are supplied with dual/redundant power inputs and being multi voltage they should work on 18 to 30VAC, and 12 to 48VDC powered systems.
The switches are designed to be DIN rail mountable, compact, rated to IP30 and have an operating temperature range of -10 to +60 degrees C.
The switches should also feature full LED Link/ACT indication and dual LED power supply indication, as well as including selectable storm protection.
