Comnet CNFE3FX1TX2C8RX-M Industrially Hardened 10/100 Mbps 3-Port Intelligent Ethernet Switch

The CNFE3FX1TX2C8RX-M from Comnet is an industrially hardened three-port intelligent switch with light management functionality and an integrated contact closure server. The 100BASE-FX port supports conventional CAT-5e/CAT-6 copper or optical transmission media by selection of the appropriate ComNet SFP module. A summary fault alarm provides indication via a form c relay in the event of loss of optical link or operating power. The 10/100BASE-TX ports support both auto-negotiation and automatic MDI/MDI-X crossover for full and half-duplex operation; manual MDI/ MDI-X switching is not required. The integrated contact closure server is available with 4 or 8 channels and supports individual user selectable wet or dry inputs. Form A relay outputs feature individual user selection of normally open or normally closed operation via the built-in web GUI. The contact server supports 4 modes of operation including one-to-one, one-to-many, many-to-one and stand-alone use through JSON frames for integration into third party systems.

The internal/self-contained 9 to 36 VDC or 24 VAC power supply features redundant power inputs, for the highest possible reliability. The simple to install, CNFE3FX1TX2C8RX-M Series is DIN-rail or panel-mountable, and is ideal for mission-critical applications where very high levels of reliability and network availability are of the utmost importance.

Features

• Full duplex transmission of 10/100 Mbps Ethernet: (2) 10/100BASE-TX ports and (1) 100BASE-FX SFP port
• Extended ambient operating temperature range of -40º to +75º C, for use in virtually any environment. Optional conformal coating available for humidity with condensation or airborne particulate matter environments
• Uses customer-installed ComNet SFPs for compatibility with a wide range of optical fibers, optical connector types, and optical transmission distances of up to 120 km
