AJ65BT-68TD Description

AJ65BT-68TD Key Features

• 8-Channel Thermocouple Input: Supports 8 differential input channels for a wide variety of standard thermocouples (B, R, S, K, E, J, T).
• Wide Temperature Range: Measures temperatures from -200°C to 1700°C, covering low, medium, and high-temperature industrial applications.
• High Precision & Resolution: Delivers high accuracy with a maximum resolution of 0.1°C (for K, E, J, T types) and 0.3°C (for B, R, S types).
• Cold Junction Compensation: Integrated Pt100 channel for automatic, accurate cold junction compensation (±1.0°C accuracy).
• Fast Conversion Speed: Provides a sampling rate of 45ms per channel for efficient multi-point temperature acquisition.
• Transformer Isolation: Full galvanic isolation (transformer-based) between input channels and the CC-Link network, ensuring superior noise immunity and signal integrity.
• Flexible Data Output: Outputs both 16-bit signed binary temperature data and scalable values (0 to 2000) for direct controller integration.
• CC-Link Compatibility: Operates as a remote device station on standard CC-Link networks, occupying 4 stations.
• Individual Channel Configuration: Each channel can be independently configured for thermocouple type, range, and filtering.
• Industrial Durability: Robust construction resistant to vibration, shock, and wide temperature/humidity fluctuations.
• Global Certifications: Conforms to UL, cUL, CE, and RoHS standards for global industrial use.
