Serial Redundancy Switch Model SRS 201:

SRS 201 has been designed to cater to communication redundancy requirements. It is very flexible and all the 3 Ports are RS232 / RS485 / RS422 configurable. It can enable 2 SCADA Masters talk to a common RTU or a single SCADA master to talk to Redundant RTU’s on field. It can enable 2 SCADA Masters talk to a common RTU or a single SCADA master to talk to Redundant RTU’s on field. It can also be connected through a PLCC modems etc During Power On, whichever Master sends a query, is connected to the Output ( Slave ). Incase your Master Port fails or Cable from your Primary Master to our Port has failed then SRS senses “No Communication” between the Primary Master & the Slave & bumplessly switches communication to your Secondary Master. Time Out is selectable from 1 Sec. to 9 Sec. SRS will wait up to the Time Out in order to establish other connection. Manual selection of the ports is provided for easy diagnostics. It is expected that during this time your Auto Redundancy logic will also start sending queries from the Secondary master.
