TC2900
Multi-Drop Fiber Optic Multiplexer (Bus/String: RS232/422/485)

Designed for Bus or String topologies, the TC2900 Multi-Drop Fiber Optic Multiplexer interconnects up to 12 Remote Terminal Units (RTU's) or Programmable Logic Controllers (PLC's) in Utility substation & SCADA networks requiring multiple channels. It is also used for similar connectivity applications in Traffic Control, Industrial Process and Security System networks.

The TC2900 works in "poll-response" (also called Slave/Master) types of communication networks. RS-232 and RS-485 interfaces are independent and operate over single mode or multimode fiber.

It is available with multiple masters for maximum reliability. Fault conditions are detected both Tx and Rx, upstream & downstream of each unit, and automatically re-route data paths to maintain network integrity. Dry contact alarms can be connected to RTUs/PLCs for pinpointing fault locations.

Features
  • Bus or String Topologies
