The STL-DO4 PLC by Mitsubishi is a space-saving transistor output module that delivers efficient signal control in industrial automation environments. Part of the STLite Series, it is designed with a 24V DC power supply and a low internal current consumption of just 0.007 A, making it ideal for systems where power optimization is critical. Its four integrated digital transistor outputs operate using source logic, supporting devices that require a positive switching output. Built with cage clamp wiring, it simplifies connection and maintenance in dense control panels.
Despite its slim bodyβjust 12 mm wide and weighing only 0.04 kgβthe Mitsubishi STL-DO4 maintains excellent durability with a depth of 100 mm and height of 65 mm. This design allows easy installation on DIN rails, especially in compact or modular systems. With a rated load voltage of 24 VDC, the module ensures safe and consistent output to actuators, indicators, and other end devices. Whether used in stand-alone setups or networked with other I/O modules, this PLC supports rapid control response, helping engineers streamline operations.
The Mitsubishi STL-DO4 PLC finds wide application in compact automation panels where limited space and precision output control are key. Its source-type transistor outputs make it ideal for use with PLC-driven indicator lamps, relays, contactors, solenoids, and low-current DC loads in assembly lines or testing benches.
Indian maintenance engineers often prefer this model for packaging machines, conveyors, and labeling systems where reliability and fast signal transmission are critical. It is also a popular choice among OEMs creating modular control systems for cost-sensitive environments. Thanks to its plug-and-play wiring and compact profile, it reduces both wiring time and panel spaceβtwo vital factors in modern industrial design.
For engineering students and automation trainees, the STL-DO4 offers a practical learning platform to understand source logic output behavior, PLC I/O mapping, and signal flow. Overall, the Mitsubishi STL-DO4 PLC is a highly reliable module trusted by professionals for precise and compact automation tasks.
