Mitsubishi RX72C4 - Programmable Logic Controller

The Mitsubishi RX72C4 PLC is built for large-scale digital input acquisition, combining high-density input capacity with compact design. Part of the powerful MELSEC iQ-R Series, this module supports 64 digital inputs with 5V/12V DC signal compatibility, enabling engineers to connect a wide variety of sensors, switches, and field devices. Its connector-type wiring simplifies installation, especially in high-speed I/O systems that require modular and hot-swappable architecture.

Despite its high input capacity, the module maintains a slim profile — measuring just 27.8 mm in width, 106 mm in height, and 110 mm in depth — making it ideal for compact panels and machine cabinets. The RX72C4 consumes only 0.15 A of internal current, supporting energy-efficient operations while maintaining signal reliability. Its robust build quality ensures consistent performance even in harsh industrial environments such as automotive plants, semiconductor manufacturing, and food processing units where accuracy and speed are critical.

Known for its stability, diagnostic support, and integration flexibility, the RX72C4 has become a trusted component in Mitsubishi’s PLC systems across India and globally. It works seamlessly with other iQ-R modules and supports centralized I/O management, reducing wiring complexity and downtime. The Mitsubishi RX72C4 PLC is ideal for high-speed digital signal acquisition in industries requiring precision, modularity, and scale. One of the most common use cases is in assembly automation lines where 64 input signals need to be captured from sensors across multiple zones—ensuring fast product detection, part presence checks, and interlock logic sequencing.

In bottling plants and material handling systems, the RX72C4 helps detect product position, conveyor alignment, and reject conditions through its multi-channel inputs. This high I/O density eliminates the need for multiple modules, reducing cost and control panel size. Maintenance engineers prefer the connector-based wiring for its ease of access during servicing and troubleshooting.

Thanks to its diagnostic-ready input structure and support for both 5V and 12V DC logic levels, the RX72C4 is also used in smart factory environments where high-frequency switching, safety logic, and machine-to-machine communication are essential. For automation engineers looking to scale up without compromising reliability, the Mitsubishi RX72C4 PLC delivers consistent performance in critical applications.
