• Four digital input channels provide discrete signal acquisition for control logic processing. Keep dimensions 8.00 x 5.00 x 2.9 cm and net weight 0.03 Kg unchanged while comparing project documents and product image evidence.
• Operating voltage is specified at 24 V DC for consistent power supply requirements.
• Maximum switching frequency reaches 200 kHz for high-speed event detection tasks.
• Sourcing input type indicates current flows from the module to the connected device.
• Compact form factor fits standard DIN rail mounting systems in control cabinets.
• Active product lifecycle status confirms ongoing manufacturing and technical support review details.

• Brand designation identifies the manufacturer as Siemens within the industrial automation sector. Use the source path Automation technology / Digital modules / SB 1221 digital input modules to confirm catalog context, model family, parameter review scope, and technical inquiry preparation notes.
• Series classification places the unit within the SIMATIC S7-1200 programmable controller ecosystem.
• Module type SB 1221 denotes a specific digital input expansion board variant.
• Full part number 6ES7221-3BD30-0XB0 serves as the unique identifier for inquiry preparation requests.

Parameters are factual source fields retained for model review.

• Physical dimensions measure approximately 8.00 cm in width, 5.00 cm in height, and 2.9 cm in depth. Check product-owned images, label text, connector area, and submitted model references against the exact 6ES7221-3BD30-0XB0 record before publication.
• Net weight is recorded at 0.03 Kg, indicating a lightweight construction for easy handling.
• Input channel count remains fixed at four discrete points for signal monitoring.
• Voltage rating specifies 24 V DC operation for standard industrial control environments.
• Frequency capability supports signals up to 200 kHz for rapid response applications.

• Product images typically display the front terminal block layout for wiring reference. Review Siemens 6ES7221-3BD30-0XB0 as SB 1221 digital input modules with source category SB 1221 digital input modules, recorded lifecycle Active Product, and submitted model identity.
• Labeling on the module face includes the full part number for visual verification.
• Side views may show the DIN rail clip mechanism for mounting confirmation.
• Internal component photos are generally not provided due to proprietary design restrictions.

• Verify that the target PLC CPU supports the SB 1221 expansion module interface. Keep dimensions 8.00 x 5.00 x 2.9 cm and net weight 0.03 Kg unchanged while comparing project documents and product image evidence.
• Confirm that the field devices match the 24 V DC sourcing input requirement.
• Check physical space constraints within the control cabinet for the module dimensions.
• Review project documentation to ensure the 200 kHz frequency meets signal needs.

• Technical data is sourced directly from manufacturer product documentation records.
• All specifications are subject to change without prior notice by the maker.
• Users should consult documented Siemens resources for detailed installation and wiring guides.
• Inquiries should focus on technical suitability rather than commercial transaction terms.
