© Siemens AG 2010SIMATIC S7-1200Digital modulesSB 1223 digital input/output module■ Overview■ ApplicationThe SB 1223 digital input/output signal module permits:• Connection of the controller to digital signals of the process• Output of digital signals from the controller to the process.■ DesignThe signal boards are plugged directly into the receptacle on thefront of each S7-1200 CPU.• Mounting:Signal boards are plugged directly into the SIMATIC S7-1200CPU and are thus electrically and mechanically connected tothe CPU• The CPU mounting dimensions remain unchanged• All signal boards are easy to replace thanks to removable connectingterminals ("independent wiring")4• Digital inputs and outputs as supplement to the integral I/O ofthe SIMATIC S7-1200 CPUs• Can be plugged direct into the CPU■ FunctionThe SB 1223 digital input/output signal board converts• the level of the external digital signals from the process intothe internal signal level of the S7-1200 and• the internal signal level of the S7-1200 into the external signallevel required by the process■ Technical specificationsProduct type designation SB 1223DI 2x24 V DC, DQ 2x24 V DCSupply voltagesRated value• permissible range, lower limit (DC) 20.4 V• permissible range, upper limit (DC) 30 VPower supply to the transmitters6ES7 223-0BD30-0XB0 6ES7 223-3AD30-0XB0 6ES7 223-3BD30-0XB0SB 12232xDI / 2xDQ 5 V DC 200kHzSB 12232xDI / 2xDQ 24 V DC 200kHz• Supply current, max. 4 mA; per channel 4 mA; per channel 4 mA; per channelCurrent consumptionfrom backplane bus 5 V DC, typ. 50 mA 50 mA 50 mAPower lossPower loss, typ. 1W 1W 1WDigital inputsNumber of digital inputs 2 2 2• in groups of 1 1 1Number of simultaneously controllableinputs• all mounting positions- Concurrently controllable inputs, 2 2 2up to 40 °CInput characteristic curve acc. to Yes Yes YesIEC 1131, Type 1Input voltage• Rated value, DC 24 V 5V 24 V• for signal "0" 0 to 5 V 0 to 1 V 0 to 5 V• for signal "1" 15 to 30 V 2 to 6 V 15 to 30 VInput current• for signal "0", max.1mA 3mA 2mA(permissible quiescent current)• for signal "1", min. 6mA 5.8 mA• for signal "1", typ. 0.5 A 14 mASiemens ST 70 N · 20104/57
