QJ72LP25GE MITSUBISHI Relay Input Module

Product  Description：

The Mitsubishi Relay Input Module is a high-performance component designed for Mitsubishi Electric’s programmable logic controller (PLC) systems, such as the MELSEC-Q or iQ-R Series. These modules serve as the critical interface between external input devices—such as push buttons, sensors, and limit switches—and the PLC's processing unit. By utilizing relay isolation, these modules provide a robust barrier that protects the delicate internal circuitry of the PLC from electrical noise and voltage spikes common in industrial environments.

Product Parameters

While specific values vary depending on the exact model (e.g., QX10 or RX10), the following are standard specifications for Mitsubishi Relay Input Modules:

• Input Type: Contact input (AC or DC depending on model).

• Number of Points: Typically available in 8, 16, 32, or 64-point configurations.

• Rated Input Voltage: Commonly 100V to 240V AC or 24V DC.

• Rated Input Current: Usually between 4mA and 10mA per point.

• Response Time: Generally ranging from 1ms to 10ms for both "Off to On" and "On to Off" transitions.

• Isolation Method: Relay or Photocoupler isolation for enhanced circuit protection.

• Connection Type: Removable terminal blocks or high-density connectors.

• Status Indicators: LED displays for each input channel to show signal status.

Product Advantages

Mitsubishi relay modules are favored in heavy industry for several key reasons:

• Exceptional Noise Immunity: The physical separation provided by relay contacts makes these modules highly resistant to electromagnetic interference (EMI).

• Versatile Voltage Compatibility: Many modules can handle a wide range of input voltages, allowing for easier integration with diverse field devices.

• Durability and Reliability: Built to withstand harsh industrial conditions, these modules offer a long service life with minimal maintenance.

• Diagnostic Ease: Built-in LED indicators allow technicians to quickly troubleshoot wiring issues or device failures at a glance.

• Hot-Swapping Capabilities: On certain high-end platforms, modules can be replaced without powering down the entire system, reducing downtime.

Usage Precautions and Instructions

To ensure the longevity and safety of the module, please adhere to the following guidelines:

• Current Limitations: Never exceed the rated current per point. Overloading the circuit can weld the internal relay contacts together.

• Wiring Separation: Keep input signal wires separate from high-voltage power lines to prevent induced noise and false triggering.

• Terminal Torque: Ensure terminal screws are tightened to the specified torque. Loose connections lead to heat buildup and intermittent signals.

• Environmental Protection: Install the module within a dust-free, dry enclosure. Excessive moisture or corrosive gases will degrade the relay contacts.

• Fuse Protection: It is highly recommended to install external fuses for each common line to protect the module against short circuits in the field.

Product Applications

Mitsubishi Relay Input Modules are used across various sectors where reliability is non-negotiable:

• Manufacturing Assembly Lines: Monitoring the state of safety gates, emergency stops, and conveyor sensors.

• Automotive Industry: Integrating with robotic arms and pneumatic controllers for precise timing and sequencing.

• Water Treatment Facilities: Collecting data from float switches, pressure sensors, and valve positioners.

• Elevator Control Systems: Managing floor signals, door sensors, and limit switches for safe passenger transport.

• Food and Beverage Packaging: Interfacing with high-speed counting sensors and sorting mechanisms.
