Product Description
Mitsubishi Universal model AJ65BT-68TD Redundant Power Supply Module
AJ65BT-68TD Description
The AJ65BT-68TD is a high-precision remote temperature input module designed for industrial CC-Link fieldbus networks. It features 8 channels for universal thermocouple input plus a dedicated Pt100 cold junction compensation channel, enabling accurate temperature measurement across a wide range of industrial processes. This module converts analog thermocouple signals (types B, R, S, K, E, J, T) into high-resolution digital data, which is transmitted reliably over the CC-Link network to the main controller. Engineered for decentralized temperature monitoring in demanding environments, it offers robust isolation, multi-channel versatility, and seamless integration into automated manufacturing and process control systems.
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.
