Mitsubishi Electric AJ65BT-64RD4 CC-Link Temperature Input Module

Description

Designed for high-accuracy thermal monitoring in industrial network environments, the Mitsubishi Electric AJ65BT-64RD4 serves as a specialized 4-channel platinum resistance temperature detector (RTD) input module within the CC-Link remote I/O architecture. This module interfaces with 4-wire Pt100 and JPt100 RTD sensors, converting micro-resistance changes into highly precise digital outputs for PLC integration.

The unit features customizable resolution configurations, outputting either 16-bit signed binary values for standard setups or 32-bit signed binary values for applications requiring precise measurements up to three decimal places. Equipped with photocoupler isolation between the temperature inputs and the main CC-Link transmission lines, the module protects sensitive control circuitry from field-side electrical surges and noise interference.

Features

• Supports up to 4 independent temperature measurement channels using high-stability 4-wire RTD configurations.
• Compatible with both Pt100 and JPt100 platinum resistance temperature detectors.
• Flexible digital output options: 16-bit signed binary (-1800 to 6000) or 32-bit signed binary (-180000 to 600000).
• Outstanding measurement resolution of 0.025 degC for high-precision thermal tracking.
• Fast conversion speed of 40 ms per channel, ensuring near real-time thermal response.
• Secure photocoupler isolation between the measurement terminals and the CC-Link communication bus.

Applications

• Precision temperature monitoring in chemical processing and petrochemical plants.
• Environmental chamber and industrial HVAC control.
• Boiler and furnace thermal loop feedback systems.
• Process control monitoring in food, beverage, and pharmaceutical manufacturing.

Connections and Interfaces

Installation Guidelines

• Mounting: Install within a secure, dust-free control cabinet. Mount securely using integrated DIN rail connectors or direct screw mounting.
• Wiring: Use CC-Link dedicated high-shield cables for network communication. Ensure the 4-wire RTD signal lines are routed away from high-voltage AC cables to prevent electromagnetic coupling.
• Grounding: Connect the ground terminal securely to the panel earth ground using a dedicated wire of 2 mm² or larger to assure optimal noise immunity.

Compliance and Certifications

• Meets IEC 61131-2 specifications for programmable controllers.
• Conforms to JIS B 3502 vibration and impact resistance standards.
