The contact-mapping ComNet™ CNFE8(X)COE transmits eight contact closures over an Ethernet network. It is available with a 10/100TX RJ45 Ethernet connector and an SFP fiber optic interface. These units can be one-to-one mapped over Ethernet or controlled via a PC. Included is a driver that allows the CoE to read or write contact information from a PC based application. A software utility allows customers to search for this device that is installed on the network. The CNFE8TCOE transmitter and CNFE8RCOE receiver support Windows® Discovery. Distances depend on which SFP (Small Form Pluggable) module is used. The CNFE8(X)COE is environmentally hardened to operate in extreme temperatures. LED indicators are provided for confirming operating status. Packaged in the ComNet ComFit housing, these units may be either wall, rack, or DIN-rail mounted with the addition of the ComNet DINBKT1 adaptor plate.
