Mitsubishi RX40NC6B - Programmable Logic Controller

The Mitsubishi RX40NC6B is a powerful DC input module equipped with 16 integrated digital inputs, built to handle 24 VDC signals in real-time with built-in diagnostic functions. As part of the MELSEC iQ-R Series, this module supports complex automation systems that require fast response, error detection, and enhanced monitoring across high-speed machinery.

Engineered for compact control panels, it measures just 27.8 mm in width and 98–106 mm in height, with a depth of 131 mm. Despite its lightweight profile of only 0.25 kg, the RX40NC6B occupies 32 I/O points, offering high signal density per module. Its 0.45 A internal current consumption is optimized for efficient operation in energy-sensitive environments. With robust screw-type terminals and rugged build quality, it ensures vibration-resistant wiring and dependable long-term performance on shop floors.

In demanding industrial environments, the RX40NC6B PLC module stands out for its error-checking functionality and diagnostic feedback. These features allow engineers to detect abnormal signal patterns, wiring issues, and power fluctuations without relying on external monitoring tools. When paired with Mitsubishi’s GX Works3 software and networked with iQ-R CPUs, it supports seamless integration and system-wide transparency. The Mitsubishi RX40NC6B PLC is ideal for applications that demand real-time input feedback, safety assurance, and error diagnostics. It’s commonly used in manufacturing automation, material handling systems, packaging lines, and automotive assembly plants—where the ability to detect faults and signal loss early is critical to maintaining uptime.

In AC-to-DC conversion zones or safety circuits, this module excels due to its 24 VDC input compatibility and diagnostic intelligence. For example, in bottling and conveyor automation, the RX40NC6B helps detect signal delays or broken sensors before they impact production. Indian maintenance engineers often rely on its intuitive error flagging to troubleshoot issues quickly, without needing external diagnostic tools.

Whether you're retrofitting legacy PLCs or scaling up new automation projects, the RX40NC6B brings both advanced monitoring and cost-effective performance to your control system. Its precision diagnostics, compact footprint, and seamless integration with the Mitsubishi iQ-R platform make it one of the most trusted PLC input modules in the industry today.
