Applications

The TC2850 is often used for applications requiring virtual point-to-point configurations, such as a dedicated telephone circuit, within a Self-Healing Ring network. It is also used in larger networks with multiple port SCADA Host Controllers to speed up polling times. Typical application environments include SCADA, Traffic Control, Process Control, Security, Oil & Gas, and Energy Management.

Description           

The TC2850 Fiber Optic Self-Healing Ring Multiplexer features the potential benefits of Channel Mapping:

• Two independent communications networks(e.g. SCADA networks) in one self-healing ring topology

• Cost savings through flexible channel configurations

• Faster polling rates.

Channel Mapping enables users to configure specific channels from the Master (Model TC2850) to designated Slave units (Model TC2851 & TC2852) on a fiber ring. Designated channels could include both a dedicated virtual point-to-point channel and a broadcast poll-response channel on each Slave.

The TC2850 offers a sophisticated Self-Healing Ring scheme and is available with dual masters for maximum reliability.  Fault conditions are detected both Tx and Rx, upstream and downstream of each unit, and automatically re-routed to maintain Ring integrity.  Dry contact alarms can be connected to RTUs/PLCs to help pinpoint the location of a fault.

It is transparent to all protocols, supports data rates up to 120 Kbps and is compatible with RS-232, RS-422 or RS-485 (2- or 4-wire) interfaces over single mode or multimode fiber.  Options include Hardened Temperature versions (-20°C to 70°C & -40°C to 80°C) for extreme environments and Conformal Coating to prevent corrosion, etc.

The Master (TC2850) and Slave (TC2851 & TC2852) units each have two pairs of fiber optic ports, one primary and one secondary.  On the electrical side, the Master(s) can have 4, 8 or 12 ports. The TC2851 Slave has four RJ11 ports providing four independent channels. Optical signals are regenerated at each Slave (drop). Each TC2852 Slave has two pairs of RJ11 ports providing two independent, redundant channels.

The TC2850 is compatible with all popular types and sizes of fiber optic cable.  Fiber connectors are ST or FC.  Electrical connectors are RJ11 female.  Standard power is 12VDC.  Optional power sources are 24VDC, 125VDC or 115/230VAC with an external power cube.
