LX40C6 MITSUBISHI MELSEC iQ-R Series 16-Point Digital Input Module

The LX40C6 MITSUBISHI (Model: LX40C6) is a high-speed, high-reliability 16-point digital DC input module engineered for the Mitsubishi Electric MELSEC iQ-R Series Programmable Automation Controller (PAC) platform. Operating at 24V DC, the LX40C6 MITSUBISHI accepts both sink and source (positive/negative common) wiring configurations, providing rapid input signal acquisition for complex factory automation, motion control, and high-density industrial telemetry systems.

Equipped with an 18-point removable screw terminal block, the LX40C6 MITSUBISHI features ultra-fast hardware response times (configurable from $0.1\text{ ms}$ to $70\text{ ms}$) and optical isolator coupling for complete noise immunity between field sensing circuits and the iQ-R system backplane. Bright channel-status LEDs and diagnostic indicators allow instant visual troubleshooting of field switches, proximity sensors, and safety interlocks.

Key Features of the LX40C6 MITSUBISHI

• MELSEC iQ-R High-Speed Backplane Interface: Plugs natively into iQ-R series base units, leveraging high-speed bus communication for minimal scan overhead.

• 16-Point Universal 24V DC Inputs: Supports both sink (NPN) and source (PNP) input field wiring for maximum sensor compatibility.

• Selectable Hardware Response Filters: Input response filter times can be set ($0.1\text{ ms}$, $0.2\text{ ms}$, $0.5\text{ ms}$, $1\text{ ms}$, $5\text{ ms}$, $10\text{ ms}$, $20\text{ ms}$, or $70\text{ ms}$) to eliminate field contact bounce.

• Photocoupler Isolation Protection: Optocoupler isolation rated at $510\text{ V AC}$ protects internal PLC CPU logic against high-voltage surges and noise transients.

• Removable 18-Point Terminal Block: Facilitates rapid module replacement without disconnecting individual field control wires.

• Comprehensive Diagnostic LED Array: Features individual channel LEDs ($0–F$) and module run status indicators for rapid panel inspection.

Primary Applications

• High-Speed Factory Automation: Capturing signals from optical sensors, limit switches, proximity detectors, and encoders

• Marine SCADA & Telemetry Cabinets: Interfacing alarm contact outputs, fuel tank switches, and valve positions with iQ-R control systems

• Process & Packaging Skids: Monitoring discrete operator pushbuttons, interlocks, and safety curtain inputs in high-throughput production lines
