Ethernet Redundancy Switches

Ethernet Redundancy Switches

Achieve Cable level Redundancy in a Ethernet Network
Function-Normally in any network, as per diagram shown below, default Communication will be through Master port. As soon as data stops coming from Master port, due to some problem or cable fault, Redundant Ethernet switch automatically senses the failure & changes over to the Redundant port & starts communicating.

When fault is repaired & Data starts coming from Master port it again automatically changeovers to the Master port and starts communicating. Even if the Power supply to the switch is lost or Ethernet Redundant Switch stops responding, default connectivity will always be ON through Master port. LED indication is available to indicate which port is Active.

Redundancy Switches

The SRS finds application as a Redundancy Switch. SRS can be configured as a RS232 or RS485 Redundancy Switch. Any combination of RS232 and RS485 at either the Input or at the Output can be selected. It has 2 Input Ports e.g. a Primary and a Secondary Master & 1 Output Port e.g. a Slave. During Power On, whichever Master sends a query is connected to the Output ( Slave ). In case both the Masters are active then SRS will lock to the Primary Master. Time Out is selectable from 15 Sec. to 1Min. SRS will wait upto the Time Out. Incase your Primary Master Port has failed or Cable from your Primary Master to our Port has failed then SRS sense “No Communication” between the Primary Master and the Slave and switches communication to its Secondary Master, after the Time Out period. It is expected that during this time your Auto Redundancy logic will also start sending queries from the Secondary master.
