- Model: CAI04
- Product Type: Analog Input Module
- Manufacturer: ABB
- Core Function: Converts and transmits external analog signals to the host control system for real-time monitoring and control.
- Input Channels: 4 independent analog input channels (configurable for different signal types).
- Supported Input Signal Types:
- Voltage signals: Typically 0–10 VDC, ±10 VDC (full-scale range, subject to official confirmation).
- Current signals: Optional 4–20 mA DC (passive/active input, depending on system configuration).
- Input Impedance:
- ≥100 kΩ (for voltage input); ≤250 Ω (for current input).
- Accuracy: ±0.1% of full scale (at 25°C operating temperature; accuracy may vary slightly with temperature).
- Resolution: 12-bit (or higher, based on specific product version).
- Power Supply: Derived from the connected ABB host system (typical: 24 VDC ±10%; no independent external power required).
- Dimensions: Compact design for panel/rail mounting (typical: Width ≈ 45 mm, Height ≈ 100 mm, Depth ≈ 120 mm; confirm with official datasheet).
- Weight: Approximately 0.2–0.3 kg (net weight).
- Protection Class: IP20 (suitable for indoor control cabinet environments; dust-protected, not water-resistant).
- Operating Temperature Range: -10°C to +55°C (industrial standard operating environment).
- Storage Temperature Range: -25°C to +70°C.
- Humidity Resistance: ≤85% RH (non-condensing; avoid moisture accumulation to prevent circuit damage).
- Mounting Method: Standard 35 mm DIN rail mounting (compliant with IEC 60715) for easy integration into control cabinets.
- Compatibility: Designed for ABB ACS800/ACS880 series drives or ABB AC500 series PLCs (confirm exact system compatibility with ABB technical documentation).
- Wiring Interface: Screw terminals (for secure cable connection; recommended wire gauge: 0.5–2.5 mm²).
- Safety Standards: Complies with IEC 61010-1 (safety requirements for electrical equipment for measurement, control, and laboratory use).
- EMC Compliance: Meets IEC 61800-3 (electromagnetic compatibility for adjustable speed electrical power drive systems) to reduce interference with surrounding devices.
