Mitsubishi RY40PT5B-AS - Programmable Logic Controller

The RY40PT5B-AS PLC by Mitsubishi is a SIL2-rated analog control output module tailored for environments requiring high signal integrity and dependable analog switching. This model supports 24 V DC power input and integrates 16 transistor-based source-type outputs, enabling smooth interfacing with external loads such as analog actuators, signal conditioners, and proportional valves. The output logic design ensures clean signal flow, particularly useful in critical process applications where signal noise or voltage drop could affect equipment performance. With a compact housing of 27.8 mm width, 106 mm height, and 131 mm depth, this PLC module is optimized for space-constrained cabinets. It draws an internal current of only 0.19 A, helping maintain energy efficiency while delivering stable output operation. The screw terminal wiring provides secure, vibration-resistant connections that are ideal for harsh industrial conditions. Its 32 I/O point occupation makes it an efficient addition to high-density control systems. Trusted by automation engineers across sectors like chemical processing, pharmaceutical manufacturing, and water treatment plants, the RY40PT5B-AS ensures precision analog control and long-term stability. As part of the MELSEC iQ-R Series, it integrates seamlessly with Mitsubishi’s broader control ecosystem, providing future-proofing, modularity, and compliance with international safety standards. The Mitsubishi RY40PT5B-AS PLC is ideally suited for industrial scenarios requiring precise analog signal control, such as dosing systems, temperature regulation, and servo positioning. Its source-type transistor outputs allow for stable signal transmission, making it perfect for DC-operated analog field devices used in process automation. Indian maintenance engineers appreciate the module’s rugged build and secure screw terminal wiring, especially in vibration-prone areas like bottling plants and textile mills. It simplifies wiring, reduces service time, and ensures accurate analog output without manual recalibration. Students and junior automation professionals can also understand its role clearly—converting digital PLC logic into real-world analog control—making it a key module in learning modern control theory and application. This module bridges the gap between logic processing and real-time analog actuation. Whether you’re integrating with VFDs, control valves, or analog input converters, the RY40PT5B-AS ensures smooth output, safety integrity (SIL2), and high operational reliability—qualities that define a world-class Mitsubishi PLC in industrial automation.
