CONTACT OVER ETHERNET MODULES
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.
