Siemens 6ES7221-3AD30-0XB0 is an SB 1221 signal board that adds four 5 V DC current-sourcing digital inputs to a compatible SIMATIC S7-1200 CPU. The inputs support high-speed operation up to 200 kHz and configurable input delay, making the board relevant to compact control projects that require additional fast input points without a full-width signal module. It is suitable for machine upgrades, pulse or event input integration and replacement work. Before ordering, confirm the CPU, 5 V DC sourcing signal arrangement, frequency, input delay, cable requirements, project configuration and original board label.
