Application Scenarios & Recommended Models
1. Extreme Temperature Environments
- Requirement: 32-channel DI acquisition in -40℃~85℃ conditions
- Recommended Model: 2701226 (AXL F DI32/1 XC 1F)
- Key Reason: XC extended temperature rating; 32-channel density for large-scale monitoring
2. High-Speed Signal Acquisition
- Requirement: 16-channel high-speed digital input for precision sensing
- Recommended Model: 2701722 (AXL F DI16/1 HS 1H)
- Key Reason: HS (high-speed) design with ≤100μs response time; reliable for fast signals
3. High-Current Load Control
- Requirement: 8-channel 2A DO + 16-channel DI for heavy actuators
- Recommended Model: 2702291 (AXL F DI16/1 DO8/2-2A 2H)
- Key Reason: 2A high-current DO handles heavy loads; mixed I/O reduces module count
4. Large-Scale Digital Input Integration
- Requirement: 64-channel digital input for large automation systems
- Recommended Model: 2701450 (AXL F DI64/1 2F)
- Key Reason: Ultra-high 64-channel density; saves cabinet space for large-scale setups
5. Industrial Counting & Metering
- Requirement: 2-channel counter for production line metering (extreme temp)
- Recommended Model: 2701239 (AXL F CNT2 INC2 XC 1F)
- Key Reason: 2-channel INC2 counter; XC rating for harsh production environments
6. System Base Mounting
- Requirement: H-type base for AXL F module installation
- Recommended Model: 2700992 (AXL F BS H)
- Key Reason: H-configuration base; compatible with corresponding AXL F modules
Core Advantages
- Modular Flexibility: Diverse DI/DO channel counts (8~64) and mixed I/O options fit varied needs
- Harsh Environment Adaptability: XC extended temperature and HS high-speed variants for extreme conditions
- High-Current Capability: 2A DO variants handle heavy industrial loads (actuators, valves)
- Space-Saving Design: Compact modular layout maximizes control cabinet utilization
- Industrial-Grade Reliability: 2kV isolation, -25℃~70℃ standard temp range, and IP20 protection
- Seamless System Integration: Compatible with AXL F base systems and accessories for easy deployment

Installation & Usage Notes
- Voltage Matching: Ensure DI input voltage matches module rating (24DC vs. 110/220DC)
- Base Compatibility: Select BS (base system) and BP (base plate) matching module configuration (H/F/SE4/SE6)
- Current Limitation: Do not exceed 2A per channel for 2A DO variants; use contactors for loads >2A
- Mounting Spacing: Reserve ≥5mm between modules for heat dissipation, especially for XC/HS variants
- Wiring Specifications: Use 0.14~2.5mm² conductors; shielded cables for high-speed signal lines
- XC/HS Deployment: For XC models, confirm -40℃~85℃ operating range; for HS models, use short signal cables
- Maintenance Checks: Regularly inspect module connections and base system integrity; clean terminals periodically
