Siemens 6ES7221-3BD30-0XB0 is a compact SIMATIC S7-1200 Signal Board (SB 1221) designed to expand your PLC’s digital input capabilities without increasing its footprint. It provides 4 Digital Inputs at 24V DC with a high-speed frequency of 200 kHz, ideal for sourcing input applications.
The SIMATIC S7-1200 SB 1221 is a high-performance digital input expansion board specifically engineered for the Siemens S7-1200 PLC series. This Signal Board (SB) plugs directly into the front of the CPU, allowing for a space-saving installation. It is particularly effective for applications requiring rapid signal detection, such as pulse catching or high-speed counting up to 200 kHz.
Space Efficient: Since it mounts directly onto the CPU, it adds functionality without occupying extra DIN rail space.
High-Speed Processing: With a 200 kHz capability, it is perfect for high-frequency pulse detection and precision timing.
Seamless Integration: Designed for the SIMATIC S7-1200 ecosystem, ensuring easy configuration via TIA Portal.
Cost-Effective: Ideal for adding a small number of I/O points without purchasing a full-sized expansion module.
Input Type: 4 Digital Inputs (Sourcing/P-switching).
Rated Voltage: 24V DC.
High-Speed Inputs: Supports frequencies up to 200 kHz for specialized industrial tasks.
Diagnostic Support: Integrated LED displays for easy status monitoring and troubleshooting.
Protection: Robust design suitable for industrial environments.
