lowing safety level can be achieved, depends on the number of brakes connecting to the SBC output
terminal.
• Connection SBC output terminal to one brake: SIL2/PLd
• Connection SBC output terminal to two brakes: SIL3/PLe
About the connection of SBC output terminal, refer to 8-9-4 Connection Method on page 8-117.
