Features:
- Four 5 V DC current-sourcing inputs
- Operation up to 200 kHz
- Parameterizable input delays
The Siemens 6ES7221-3AD30-0XB0 is a SIMATIC S7-1200 SB 1221 signal board with four 5 V DC current-sourcing digital inputs. The inputs are arranged as one group of four channels. Operation up to 200 kHz supports the high-speed input functions described in the Siemens documentation. Parameterizable input delays allow the channel response to be coordinated with the application.
Typical current consumption from the 5 V DC backplane bus is 40 mA. Typical power loss is 1 W, and the maximum shielded twisted-pair cable length is 50 m. The signal board measures 38 x 62 x 21 mm for installation in the supported controller position. Its electrical ratings should be observed when connecting the external input devices.
Select this board when a compatible S7-1200 CPU requires four additional 5 V DC sourcing inputs in the documented signal-board format. Engineering should confirm the input voltage, signal frequency, delay settings and common reference arrangement. Shielding and cable routing should follow the requirements for the selected operating frequency. CPU compatibility and the STEP 7 hardware configuration must be verified before commissioning.
High-speed 5 V DC input applications using the 6ES7221-3AD30-0XB0 can be reviewed for compatibility, official documentation and sourcing through Apter Power. Siemens states product phase-out from 1 November 2026; availability is checked for each quotation.
