Mitsubishi Electric FX2N-16MR-DS FX2N Series Base Unit

Description

Integrated control and high-speed processing define the FX2N-16MR-DS, a compact base unit belonging to the renowned FX2N series of programmable logic controllers. Engineered for robust execution in heavy-duty environments, this controller features 8 digital inputs and 8 relay outputs, managed within a space-saving chassis. Operating on a 24V DC power supply, it offers an efficient architecture for localized machine automation and decentralized control tasks. The unit serves as the processing foundation, allowing seamless integration with auxiliary expansion blocks and specialized communication modules to scale overall system capacity as needed.

Features

• Equipped with 8 digital inputs (24V DC, sink/source selectable) and 8 relay outputs for versatile load switching.
• Powered via 24V DC, suitable for mobile applications, control panels, and field-mounted enclosures.
• Expandable bus connection allows the integration of additional digital, analog, and communication expansion blocks.
• Integrated run/stop switch on the front panel for simplified testing and local maintenance.
• High-speed processing capability suitable for real-time logic execution, sequencing, and timing tasks.
• Removable terminal blocks facilitate direct, secure wiring and rapid module replacement.

Applications

• Pumping stations and automated water treatment systems.
• Conveyor networks, sorting systems, and material handling lines.
• HVAC control systems and building automation distribution panels.
• Packaging, labeling, and small-scale assembly machinery.

Installation Guidelines

• Mounting: Attach securely to a standard 35mm DIN rail or screw directly to an earthed backplane panel. Keep a minimum spacing of 50mm on all sides for passive cooling and terminal access.
• Grounding: Connect the FG (Frame Ground) terminal to a dedicated, low-impedance functional ground (Class D grounding, 100 ohms or less) to minimize electromagnetic interference.
• Wiring: Route high-voltage AC output wires separate from low-voltage DC input and communication signal cables to avoid signal crosstalk. Use crimp terminals matching the M3 terminal screws.
