Q38RB MITSUBISHI Output Module

Product  Description：

Mitsubishi Electric offers a diverse range of output modules primarily for their MELSEC series PLCs (Programmable Logic Controllers), such as the iQ-R, iQ-F, Q, and L series. These modules serve as the interface between the PLC’s internal logic and external field devices like solenoids, motors, and lamps.

Technical Specifications

The specifications for these modules vary depending on the specific model and series, but they generally fall into three categories based on the switching element used:

• Relay Output Modules: These use mechanical relays to switch loads. They are versatile, supporting both AC and DC voltages, and typically handle up to 2A per point.

• Transistor Output Modules: Designed for high-speed switching of DC loads. They come in "Sinking" (NPN) or "Sourcing" (PNP) types. Standard operating voltages are 12V DC to 24V DC.

• Triac Output Modules: Specifically designed for switching AC loads. These are ideal for applications involving 100V AC to 240V AC where silent operation and high frequency are required.

Common technical parameters include the number of output points (ranging from 8 to 64 points per module), response times (often less than 1ms for transistors), and isolation methods (typically optical or mechanical) to protect the CPU from electrical surges.

Product Advantages

Mitsubishi output modules are recognized for their industrial-grade reliability and modular flexibility.

One primary advantage is the high density of points available in a single slot, which saves significant space within the control cabinet. They feature advanced diagnostic capabilities, such as short-circuit protection and thermal protection in specific transistor models, which helps prevent hardware damage during a field fault. Furthermore, the ease of maintenance is enhanced by removable terminal blocks, allowing for quick module replacement without the need to rewire every individual point.

Important Considerations and Precautions

When selecting and installing these modules, certain precautions are necessary to ensure longevity and safety.

First, always verify the load current and ensure it does not exceed the module's rated capacity per point or the total common terminal capacity. For inductive loads, such as large motors or magnetic valves, it is crucial to install external surge suppressors (diodes for DC or varistors for AC) to prevent back-EMF from damaging the module's internal circuitry.

Additionally, be mindful of the leakage current. Transistor and Triac modules have a small amount of leakage even in the "OFF" state, which might keep very low-power loads (like small LEDs) energized.

Typical Applications

Mitsubishi output modules are utilized across various industries to automate physical actions.

In manufacturing, they control pneumatic valves on assembly lines and trigger conveyor motor starters. In food and beverage processing, they manage the timing of filling and packaging actuators. They are also widely used in building automation for controlling lighting systems and HVAC dampers, as well as in energy management systems for switching circuit breakers or status indicators.
