Detailed content
Technical Specifications:
- Channels: 32 isolated digital input channels (grouped in 8-channel isolated groups)
- Input Voltage Range: 18–30 VDC (24 VDC typical, allowing ±15% fluctuation)
- Input Current Range: 0–10 mA
- Isolation: Each input channel has independent isolation barrier; isolation prevents ground loops
- RC Filter: Each channel equipped with RC filter circuit to suppress transient interference from contactor switching
- Operating Temperature: -40 °C to +85 °C (industrial wide temperature)
- Humidity: 5% to 95% RH, non-condensing
- Mechanical: 0.45 kg aluminum reinforced housing, DIN rail mounting
- Dimensions: 19 inch × 3.5 inch × 8 inch
- Weight: 10 lbs (as per some sources); approx. 0.45 kg (aluminum housing)
- Certifications: CE, UL, IEC 61000-6-2
- Communication: Supports Modbus RTU/TCP protocols
Functional Features: Electrical isolation technology suppressing electromagnetic interference; intelligent diagnostics with status indicator LEDs (green-normal/red-fault); redundant power supply design; supports hot-swappable replacement during system operation; compatible with PLC, DCS, and SCADA systems.
Application Scenarios: Factory automation, building automation, power, chemical, manufacturing—especially suitable for production line control systems requiring continuous operation.
Performance Parameters: Effectively reduces false triggering risks; enhances system response speed; maintains stable operation during power fluctuations.
Material Composition: Aluminum reinforced housing, plastic shell reaching IP20 protection grade.
Structural Features: Compact design with modular structure for rapid on-site installation and maintenance; suitable for space-constrained control cabinets.
Working Principle: Uses electrical isolation technology per channel to accurately acquire switch signals, with RC filtering to suppress transient interference; transmits collected signals via Modbus RTU/TCP protocol.
Installation Requirements: DIN rail installation; requires stable 24 VDC power supply (allowing ±15% fluctuation); redundant power input interfaces available for automatic switching upon single power failure.
Usage Precautions: Use shielded twisted pair wiring for field switch signals, ensuring correct polarity and proper grounding to prevent ground loops. Check LED indicators regularly for channel status.
