Unité de contrôle de température Q 64 TCRTN

Description

Precision thermal regulation in automated systems requires reliable, high-speed feedback and control. The Mitsubishi Electric Q64TCRTN is a high-performance, 4-channel temperature control module designed for seamless integration with the MELSEC-Q Series PLC platform. Operating as an intelligent function module, this unit directly interfaces with Pt100 and JPt100 resistance temperature detectors (RTDs) to deliver accurate monitoring and closed-loop PID control without placing overhead on the main CPU.

Equipped with four independent input channels and corresponding transistor outputs, the Q64TCRTN utilizes an advanced auto-tuning PID algorithm to maintain stable process variables. This makes it highly compatible with demanding thermal management systems in plastics extrusion, packaging machinery, chemical processing, and environmental chambers. Its isolated architecture ensures robust protection against electrical noise and ground loops in harsh industrial environments.

Features

• Multi-Channel Input: Supports 4 independent temperature measurement channels using standard Pt100 or JPt100 RTD sensors.
• Flexible Control Modes: Configurable for PID control (with auto-tuning), ON/OFF pulse control, or direct 2-position control.
• High-Speed Processing: Fast 500 ms sampling cycle across all 4 active channels ensures responsive control actions.
• Robust Insulation: Built-in transformer isolation between the input terminals, the sequencer power supply, and individual input channels.
• Disconnection Safety: Features automatic upscale processing in the event of sensor input disconnection to protect downstream hardware.

Applications

• Plastic extrusion and injection molding temperature control.
• Food processing and packaging heat-seal systems.
• Chemical and pharmaceutical reactor thermal regulation.
• Semiconductor manufacturing cleanroom climate control.

Installation Guidelines

• Rack Mounting: Securely insert the module into a standard MELSEC-Q series base unit, ensuring the module fixing hook is fully engaged.
• Terminal Wiring: Use M3 crimp terminals for all connections to the 18-point terminal block. Tighten terminal screws to the recommended torque limit of 0.42 to 0.58 N-m.
• Noise Mitigation: Route sensor input wiring separately from high-voltage AC power lines and motor drives to prevent electromagnetic interference.
• Shielding: Connect the shield wire of the RTD cable to the designated ground terminal on the module or the panel enclosure.
