3. Advantages and Features

• High-Precision Signal Conversion:
  The 2263117 leverages advanced analog-to-digital conversion technology to minimize signal distortion, achieving a signal-to-noise ratio of 90 dB for analog inputs. This precision is critical for applications like quality control in automotive manufacturing, where accurate sensor data reduces scrap rates by up to 25%.
• Modular Scalability:
  Its daisy-chain capability allows seamless integration of up to 32 modules in a single network, supporting systems with hundreds of I/O points without complex cabling. This feature reduces installation time by 40% compared to non-modular alternatives.
• Energy-Efficient Operation:
  The module enters a low-power sleep mode during idle periods, reducing power consumption by 70% without compromising responsiveness. In a 24/7 production line, this translates to annual energy savings of 15–20%.
• Rugged Industrial Design:
  The IP65-rated enclosure protects against dust and water jets, while the wide temperature range ensures reliable operation in challenging environments such as steel mills or outdoor machinery, where temperature fluctuations and moisture are common.

4. Application Areas and Case Study

Application Areas:

• Automotive Manufacturing: Press lines, robotic assembly cells, and conveyor systems requiring precise sensor integration.
• Aerospace: Test benches for hydraulic actuators and fuel system control.
• Metallurgy: Continuous casting machines and rolling mills with harsh environmental conditions.
• Industrial Machinery: Packaging equipment, injection molding machines, and CNC machine tools.

Case Study:

5. Competitive Comparison

• Higher Channel Density: 24 total I/O channels in a compact form factor, providing 20% more channels than comparable modules of the same size.
• Enhanced Safety Features: Built-in SIL 2-rated protection reduces the need for external safety components, lowering system costs by 15%.
• Wide Protocol Support: Native compatibility with both CANopen and PROFIBUS DP, offering flexibility in multi-vendor environments where single-protocol modules may require costly adapters.
• Extreme Environment Resistance: Operates reliably in temperature and humidity ranges that exceed industry standards, making it a top choice for harsh industrial sites.

6. Selection Recommendations

• I/O Requirements: Choose the 2263117 for applications needing a mix of analog and digital channels (8 AI + 16 DI/DO). For higher analog channel counts, consider Rexroth’s specialized analog modules.
• Communication Needs: Opt for this module if your system uses CANopen or PROFIBUS DP; for Ethernet-based networks, explore Rexroth’s Ethernet-compatible I/O solutions.
• Environmental Fit: Verify that your operational environment’s temperature (-25°C to +60°C) and moisture levels (≤95% non-condensing) match the module’s specifications, especially for outdoor or washdown applications.
• Scalability Plans: If future system expansions are expected, leverage the module’s daisy-chain capability to ensure seamless integration without major hardware changes.

7. Precautions

• Installation:
  • Mount the module horizontally in a well-ventilated enclosure, leaving at least 20 mm of clearance for heat dissipation.
  • Use shielded twisted-pair cables for signal connections to minimize electromagnetic interference (EMI), and ensure proper grounding to protect against voltage surges.
• Configuration:
  • Configure the module using Rexroth’s dedicated software or compatible third-party tools, ensuring correct signal scaling and communication parameters. Back up configurations regularly to prevent data loss during firmware updates.
  • Validate safety functions (e.g., overcurrent protection) during commissioning to ensure compliance with local safety standards.
• Maintenance:
  • Inspect the enclosure seals annually to maintain IP65 protection, replacing them if signs of wear or damage are detected.
  • Clean the module’s exterior with a dry cloth or compressed air to remove dust and debris, particularly in high-dust environments.
• Safety Practices:
  • Disconnect the power supply and wait at least 5 minutes for residual voltage to dissipate before performing maintenance.
  • Avoid modifying the module’s firmware or hardware without manufacturer authorization, as this may compromise safety certifications and operational reliability.
