The IFS D7400RHS Series Ethernet transceivers provide transmission of (3) 10/100 Mbps Ethernet data signals in a redundant, self- healing ring network architecture utilizing one optical fiber. The transceivers feature 3 electrical and 2 optical ports and can be configured in a redundant self-healing capacity that allows the user to easily configure a network that is highly reliable. The 3 electrical ports are capable of connecting at 10/100 Mbps Ethernet data 802.3 protocol using auto-negotiating and auto-MDI/MDIX features. Models within this series are available for use with multimode or single mode optical fiber and are compatible with standard 100-FX  networks. Plug-and-play design ensures ease of installation requiring no electrical or optical adjustments. Each transceiver incorporates power and link status indicating LED’s for monitoring proper system operation. In addition, 2 continuously active contact closure relays are available to activate an external audible or visual warning signal in the event of a fiber break or loss of power. The modules are available in either stand-alone or rack mount.
