The EIMK media converter from Contemporary Controls operates full duplex at 100 Mbps and is targeted at applications that require Ethernet redundancy, such as RSTP or proprietary ring networks, since its link-fault-pass-through function assures that all end devices are truly communicating with one another rather than just linking to a switch within the communication network. Faults are easy to determine and can be troubleshot quickly for correction.
Both multimode and single-mode models are available with ST or SC connectors. Fibre distances of up to 15 km are possible with the single-mode model; up to 2 km with the multimode models. On the 10/100 Mbps copper side, both MDI and MDIX ports are available to accommodate either an end station port or a switch port. Crossover functionality is accomplished on the fibre side by simply reversing fibre connections.
Built for harsh environments, the EIMK has a metal enclosure and an aluminium DIN rail clip, positive latching power terminal strip for 24 V a.c. or 24 V d.c. and redundant power input capability, and utilises shielded RJ-45 connectors. It also incorporates diagnostic LEDs, a variety of enhanced EMC compliance tests, multiple regulatory approvals, and a robust temperature range of 0°C to 60°C.
Typical applications include long distance requirements, areas with high levels of electrical noise, protection against lightning disruptions and security from wire snooping devices.
