Pilz PSS1BMP 5/2 Safety System Base Module

Product Detailed Description

• Core Functionality: The PSS 1 BMP 5/2 functions as the central processing unit or a crucial extension module within a Pilz PSS 1 safety system. It's responsible for:

• Acquiring safety-related input signals (e.g., from emergency stop buttons, safety gates, light curtains).

• Processing these signals according to programmed safety logic.

• Controlling safety-related outputs to initiate safe states (e.g., shutting down machinery, preventing hazardous movements).

• Performing internal self-monitoring and diagnostics to ensure its own integrity and the reliability of the safety functions.

• Safety Compliance: Designed and certified to meet high international safety standards, such as IEC 61508 (Functional Safety of E/E/PE Safety-Related Systems), EN ISO 13849 (Safety of machinery - Safety-related parts of control systems), and EN 62061 (Safety of machinery - Functional safety of safety-related electrical, electronic and programmable control systems). It supports applications up to the highest Performance Levels (PL e) or Safety Integrity Levels (SIL 3).

• Programming: PSS 1 systems are programmed using specialized Pilz software, allowing users to configure safety logic, assign inputs/outputs, and set parameters for safety functions.

• Modular Design: As part of the PSS 1 series, it typically integrates into a modular system where various input, output, and communication modules can be connected to expand the system's capabilities.

• Diagnostics: Features extensive diagnostic capabilities to quickly identify faults, reducing downtime and simplifying maintenance. This often includes status LEDs for inputs, outputs, and system health.

• Robustness: Built for industrial environments, offering durability and resistance to typical industrial conditions.

Product Parameters

(Note: As the PSS 1 series is older, precise, universally available parameters for "5/2" are less common. The exact parameters would be found in the specific PSS 1 BMP 5/2 operating manual or datasheet from Pilz. The following are typical for PSS 1 BMP modules.)

• System Type: Programmable Safety System Base Module

• Safety Category/Performance Level: Up to Cat. 4 / PL e (according to EN ISO 13849-1) or SIL 3 (according to IEC 61508 / EN 62061) - Requires proper system design and validation.

• Inputs: Typically safety inputs for emergency stops, safety gates, etc. The "5" in "5/2" might indicate 5 safety inputs.

• Outputs: Safety outputs for controlling contactors, valves, etc. The "2" in "5/2" might indicate 2 safety outputs.

• Supply Voltage: Often 24 V DC (e.g., 20.4 V to 28.8 V DC).

• Power Consumption: Varies by module, typically in watts (e.g., 5-15W).

• Operating Temperature: Typically 0 °C to +60 °C.

• Storage Temperature: Typically -25 °C to +70 °C.

• Protection Degree: Typically IP20 (for enclosure/terminal area).

• Mounting: DIN rail mounting.

• Dimensions: Standard modular housing for control cabinet installation.

• Communication: Internal bus for modular expansion; external communication interfaces might be available through separate modules.

• Response Time: Fast response times critical for safety applications (e.g., < 20 ms for specific functions).

Product Advantages

• High Level of Safety: Designed specifically for safety-critical applications, ensuring a high level of machine and personnel safety through redundant and self-monitoring architectures.

• Flexibility and Programmability: Allows for the implementation of complex safety logic and adaptation to various machine types and safety requirements.

• Comprehensive Diagnostics: Reduces troubleshooting time and improves system availability by quickly identifying faults.

• Cost-Effective for Complex Machines: Offers a more flexible and often more cost-effective solution than hard-wired safety relays for machines with multiple safety functions.

• Modular Expandability: Allows the safety system to be scaled according to the machine's complexity and the number of safety I/Os required.

• Proven Technology: Part of Pilz's established PSS family, which has a long history of reliable operation in safety-critical applications.

Precautions

• Expert Knowledge Required: Installation, programming, and commissioning of safety controllers like the PSS 1 BMP require specialized knowledge of functional safety standards (e.g., EN ISO 13849, IEC 61508) and Pilz's specific programming environment.

• Proper System Design: The PSS 1 BMP is a component; the overall safety of the machine depends on the correct design and validation of the entire safety control system. This includes risk assessment, selection of appropriate safety devices, and validation of the implemented safety functions.

• Correct Wiring: Adhere strictly to Pilz's wiring diagrams and safety guidelines. Incorrect wiring can lead to dangerous situations or system failures.

• Software Compatibility: Ensure compatibility between the PSS 1 BMP module, the programming software, and any other connected Pilz modules.

• Environmental Conditions: Install the module within its specified operating temperature and humidity range. Protect it from excessive vibration, dust, and moisture.

• Regular Testing & Validation: Safety functions must be regularly tested and validated in accordance with national and international standards.

• Lifecycle Management: Be aware that the PSS 1 series is an older product line. Consider long-term support, spare parts availability, and potential migration strategies for future-proof designs.
