The SRDC12 board is the key important board that is installed at Lighting Control Panel. It plays the role as mother-board for SRCC48 Controller and it has the function to operate the actual relay driving. This board is configured of circuit that operates the 12 relay and the board itself has the manual switch installed. Each relay is able to control even the program is not done. This board operates by the direct connection to each Relay.

Also, the sensor input terminal is ready with 3 EA and when it is needed, connect the sensors to use it. The one SRCC48 Controller is operated by connecting the 4 EA SRDC12 board. The 48 Relays that are mounted at this board are able for interlocking control in any combination.

ON/OFF control for 12 Relays
Plug-in modular configuration.
Monitoring the Status of Relay
Monitoring the input status for 3 program switches

SRRDC12 is operating the Bank to monitor the status and ON/ OFF of 12 Relays. It is monitoring and detecting the input of 3 Program Switches. Operate the Relay that is suitable for each and analyze the inputted command from SRCC. Transmit the feedback information to SRCC card. Each card is related with 12 EA of Relay Bank. The SRRDC is configured majorly with Relay Operation part, Feedback Contact part and PSS input part.
