6ES7221-1BF20-0XA0

The 6ES7221-1BF20-0XA0 model product is a digital input module in the Siemens S7-1200 series PLC, designed specifically for industrial automation control systems, with efficient and reliable digital signal acquisition and processing capabilities. This module supports 24V DC DC voltage input, with 16 digital input channels and a response time of ≤ 10ms. It can quickly capture changes in the status of on-site equipment and is suitable for automation scenarios that require high real-time performance. Its compact structural design saves installation space, meets industrial standard protection levels, and can operate stably in a wide temperature range of -20 ° C to+60 ° C. It is suitable for complex industrial environments such as steel, petroleum, chemical, power, building materials, machinery manufacturing, automotive, textile, transportation, and environmental protection. The module is compatible with the S7-1200 system architecture and can be seamlessly integrated into existing automation networks. It connects with sensors, actuators, and other devices through standardized interfaces, reducing the difficulty of system integration. Its high anti-interference ability and low failure rate characteristics effectively reduce the impact of electromagnetic interference on signal transmission in industrial sites, ensuring long-term stable operation of control systems. It is an ideal choice for improving industrial automation level and production efficiency.

 

Technical specifcations for 6ES7221-1BF20-0XA0

Hardware and Interface

Module type: Digital input module (SM 1221), supports 16 channel 24V DC digital signal input, compatible with standard sensors and switch devices.

Interface configuration: It adopts detachable spring terminal or screw terminal interface, compatible with PROFINET/PROFISAFE communication bus, supports hot plug technology, and is easy to maintain and replace modules on site.

Installation method: Supports DIN rail or panel installation, compatible with S7-1200 series standard rack layout, compact size (approximately 110 × 80 × 75mm), saving control cabinet space.

2、 Electrical characteristics

Input voltage: Supports 24V DC signal input, compatible with signal "0" (≤ 5V DC) and signal "1" (≥ 15V DC) logic levels, with a typical input current of 4mA and a closed-circuit current of ≤ 1mA.

Signal processing: Response time ≤ 10ms, supports standard input and alarm input modes, input delay can be parameterized (0.2ms-12.8ms, 7 levels optional), suitable for high-speed control scenarios.

Potential isolation: Channel grouping isolation (2 channels/group), isolation voltage of 500V AC, effectively blocking external interference signals and improving system stability.

3、 Protection and Certification

Protection level: IP20 protection standard, suitable for industrial environments without conductive dust, supports vertical installation (up to 50 ℃) and horizontal installation (up to 60 ℃), temperature change rate ≤ 3 ℃/minute.

Safety certification: certified by multiple countries including CE, UL, cULus, FM, RCM, KC, etc., in compliance with DIN 50020 standard, suitable for sensor connections in potentially explosive areas (Zone 1/2).

4、 Environmental adaptability

Working temperature: Supports a wide temperature range of -20 ℃ to+60 ℃, with an upper limit adjusted to 50 ℃ for vertical installation, suitable for extreme industrial environments.

Electromagnetic compatibility: Compliant with IEC 61131-2 standard, with better anti-interference ability than similar products, reducing failure rate by more than 30%, ensuring long-term stable operation of the system.

5、 Function and Diagnosis

Diagnostic capability: The module is equipped with a built-in diagnostic LED, which displays the real-time status of the input channel. It supports fault diagnosis functions such as wire breakage detection and overload alarm, and can quickly locate problems through STEP 7 Basic software.

Signal integrity: Adopting differential input design to suppress common mode interference, the wire length can reach 500m in shielded mode and 300m in unshielded mode, ensuring the stability of long-distance signal transmission.

6、 Compatibility and Scalability

System compatibility: Seamless integration into S7-1200 series PLC, supporting TIA Portal programming tool, achieving efficient data exchange with HMI, frequency converter and other devices.

Scalability: Modular design supports increasing input and output points through expansion modules, flexibly adapting to control tasks of different scales, and reducing system upgrade costs.
