MR-JE-300B MITSUBISHI I / O module

Product  Description：

Mitsubishi Electric I/O (Input/Output) modules are foundational components of the MELSEC PLC ecosystem. They act as the primary sensory and execution interface, allowing the controller to communicate with the physical world. Input modules receive signals from sensors, push buttons, and limit switches, while Output modules send commands to actuators, solenoids, and motor starters. These modules are designed to handle various signal types with high speed and reliability, ensuring that the control system can respond to field changes in real time.

Product Parameters

The technical characteristics of Mitsubishi I/O modules are tailored to specific industrial electrical standards:

• I/O Density: Available in configurations of 8, 16, 32, or 64 points per module, allowing for high-density wiring in space-constrained control panels.

• Input Voltage Ratings: Common ratings include 24V DC (Sink or Source) and 100V–240V AC, providing compatibility with global sensor standards.

• Output Switching Types: Offered in Relay (for high current and dry contacts), Transistor (for high-speed DC switching), and Triac (for AC load control).

• Response Time: Features selectable input filters, with response times as fast as 0.1ms to 70ms to prevent signal "chatter" or to capture high-speed pulses.

• Terminal Style: Designed with removable screw terminal blocks, 40-pin connectors, or spring-clamp terminals to suit different maintenance and vibration requirements.

• Isolation Voltage: Typically features 2500V AC isolation between the external field terminals and the internal PLC logic to protect the CPU.

Product Advantages

Mitsubishi I/O modules provide several engineering benefits that improve machine uptime and performance:

• Superior Diagnostic Features: Integrated LEDs for every channel allow for instant visual verification of signal status, which is critical for rapid on-site troubleshooting.

• Smart Safety and Protection: Output modules often feature short-circuit protection and thermal protection, preventing the module from failing during a field wiring fault.

• High-Speed Synchronization: When used with the iQ-R or iQ-F series, these modules support millisecond-level synchronization, essential for precision motion control applications.

• Hot-Swapping Capability: Certain high-end models allow for the replacement of modules without powering down the entire system, minimizing production downtime.

• Flexible Wiring Options: Support for dedicated interface cables and terminal conversion units simplifies the wiring process and reduces the risk of human error during assembly.

Product Applications

These modules are used throughout the automation landscape to bridge the gap between software logic and physical action:

• Automotive Manufacturing: Interfacing with proximity sensors and pneumatic valves on robotic assembly lines.

• Food and Packaging: Managing the high-speed timing of bottling lines, capping machines, and labeling equipment.

• Material Handling: Controlling conveyor systems, sorting gates, and automated storage systems (ASRS).

• Building Automation: Monitoring fire alarms, security sensors, and controlling lighting or HVAC relays.

• Water Treatment: Collecting data from level switches and controlling chemical dosing pumps.

Important Precautions

To ensure long-term reliability and safety, users should strictly follow these operational guidelines:

• Sink and Source Compatibility: Always verify whether the input module is configured for Sink (NPN) or Source (PNP) wiring. Connecting a sensor to the wrong type of module will prevent signal detection and may cause electrical issues.

• Inductive Load Protection: When using transistor outputs to drive inductive loads like solenoids, always install an external surge suppression diode to protect the module from back-EMF.

• Current Limitations: Observe the "Common" current limits. While a single point might handle 0.5A, the total current for all points sharing a single common terminal must not exceed the module's rated maximum.

• Wiring Separation: Avoid running I/O signal wires in the same conduit as high-voltage power cables (200V+). Electromagnetic interference can cause "ghost" signals or intermittent logic errors.

• Tightening Torque: When using screw terminals, ensure they are tightened to the specific torque mentioned in the manual. Over-tightening can damage the PCB, while under-tightening leads to loose connections and fire hazards.
