    "The TC2100s' Self-Healing function worked so well that several days went by before we realized that the fiber cable had been severed in one of the rings."

Applications

Renowned for its high reliability, the TC2100 Multi-Drop Modem is ideal for Ring or Self-Healing Ring communication links in SCADA, Traffic Control, Industrial Process Control and Security Networks.  It is frequently used to interconnect Remote Terminal Units (RTUs) or Programmable Logic Controllers (PLCs) in Utility substation SCADA Networks.

Description                                        

The TC2100 Multi-Drop Fiber Optic Modem provides maximum reliability for linking monitoring devices (typically RTUs or PLCs) to a Host Controller or CPU.  It is available "substation hardened" and is transparent to data or communications protocols.

The TC2100 can be configured in Ring or Self-Healing Ring topologies.  The Self-Healing Ring scheme is sophisticated, i.e. it detects upstream and downstream failures on both Tx and Rx, and automatically re-routes any cable or equipment failure.  Multiple master units for maximum reliability are optional. It supports asynchronous data rates up to 38.4 Kbps.  Electrical interfaces are RS-232, RS-422 or RS-485.  The RS-485 electrical port can be multi-dropped.  A special version, Model TC2100X, is available for extreme temperature (-40°C to 80°C) applications.

Each TC2100 unit comes standard with two pairs of fiber interfaces and either 2-Channel RS-232 or 1-Channel RS-422/RS-485 interfaces.  The second channel on the RS-232 interface can be used for data, RTS/CTS handshaking signals or as a telephone extension with the Model TC1900 "Quick-Talk" Phone Extenders.

Local and remote Loopback is standard.  Sixteen diagnostic LEDs are provided.  Dry contact alarms can be connected to RTUs/PLCs to indicate specifically where a fault has occurred.  A test signal generator for verifying link integrity is provided to aid installation and troubleshooting.  "Anti-streaming" capability is standard.

The TC2100 is compatible with all popular types and sizes of fiber optic cable and is available multimode (850/1300nm) or single mode (1300/1550nm).  Fiber optic connectors are ST or FC.  Electrical connectors are DB25 female.  Power is 12VDC; optional 24VDC, -48VDC or 115/230VAC with an external power cube.

Note: Model TC2100 is the Master unit; TC2101 is the Slave unit.
