Ethernet switches feature high port density for big systems in small panels

Downers Grove, IL—Contemporary Controls reports that its new line of industrial Ethernet unmanaged switches, EISB-B series, provides up to 24 ports of connectivity in 1.75 inches of DIN-rail space.


Downers Grove, IL— Contemporary Controls reports that its new line of industrial Ethernet unmanaged switches, EISB-B series, provides up to 24 ports of connectivity in 1.75 in. of DIN-rail space. EISB B is designed for convenient DIN-rail installation and solid performance applications requiring higher port count, while occupying minimal rack space, as well as the ability to withstand the rigors of extreme environmental conditions, such as temperatures between -40 C and +75 C.

The series is available in several models from all twisted-pair 8, 16 and 24-port models to a mix of twisted-pair and fiber-optic models of the same port count in a rugged aluminum enclosure. Both multimode (1,300 nm) and single-mode (1,300 nm) fiber optics are supported. Each port has an LED showing link/activity/data rate by color, such as green for 100 Mbps and yellow for 10 Mbps. Flashing indicates port activity.

The units can be powered from either wide-range, low-voltage ac (8-24 VAC) or dc (10-36 VAC) power sources. Redundant power connections are provided to accommodate back-up sources. Each EISB model is shipped with a DIN-rail clip installed. If direct mounting to a sub-panel is desired, the DIN-rail clip is removed and the attached mounting ears can be extended for panel mounting.
