The ComNet CNFE3FX1TX2C/M series 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.

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, CNFE3FX1TX2C/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 10/100 Mbps Bandwidth
• 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
• Extended ambient operating temperature range of -40° C to +75° C, for use in virtually any environment. Optional conformal coating for humidity with condensation or airborne particulate matter conditions
• SNMP v1/v2c for network management
• Supports Link Layer Discovery Protocol (LLDP)
• Redundant power inputs, for extremely high levels of reliability and availability
• No fans or forced-air cooling; cooling via natural convection eliminates unreliable and troublesome fans/moving parts, with no periodic maintenance requirements.
• Status indicating LEDs provide rapid indication of critical operating parameters.
• Summary fault alarm provides a local or remote indication via dry contact closure in the event of loss of optical link or operating power
• Rugged 19-gauge galvanized and powder-coated steel enclosure.
• Integrated contact closure server supports wet/dry inputs and user selectable normally open or normally closed form A relay outputs.
