TC3720
Managed Fiber Optic Ethernet Switch w/Self-Healing Ring (6Tx + 2Fx)

The TC3720 10/100M 6-Port Self-Healing Ring Ethernet Switch is a low cost solution for linking multiple RTUs & PLCs in industrial and SCADA fiber optic networks.

Intended for Self-Healing Ring topologies, the TC3720 Ethernet Fiber Optic Switch interconnects up to six 10/100M devices at each drop. Network settings can be set or changed via a Web-based configuration user interface.

Fault recovery time is less than 250 milliseconds. Fault conditions are detected on both Tx and Rx, upstream and downstream of each unit, and automatically re-routed to maintain Ring integrity. The substation hardened version supports temperature ranges from -40° C to 80°C.

It is frequently used to interconnect Remote Terminal Units (RTUs) or Programmable Logic Controllers (PLCs) in Utility substation SCADA Networks that require multiple channels and the reliability of a Self-healing Ring Topology. It is also used for similar connectivity applications in Traffic Control, Industrial Process Control and Security System Networks.

Features
