GT15-A370C12B MITSUBISHI Coupler for external

Product  Description：

Mitsubishi Electric External Network Couplers, often referred to as Network Interface Modules or Fieldbus Couplers, are the specialized gateway devices used to connect decentralized I/O stations to a main PLC controller. These modules act as the "head" of a remote I/O rack, allowing the central CPU to control sensors and actuators located hundreds of meters away via a single communication cable. They are essential for reducing wiring costs and improving system flexibility in large-scale automation projects.

Product Parameters

The technical capabilities of a Mitsubishi Coupler are defined by its network capacity and expansion limits:

• Network Compatibility: Supports high-performance industrial networks including CC-Link IE TSN, CC-Link IE Field, Profinet, and Ethernet/IP.

• Station Type: Operates as a remote station or "slave" node within the network topology.

• I/O Capacity: Capable of managing up to 64 expansion modules per coupler, supporting hundreds of digital or analog points.

• Transmission Speed: High-speed models offer 1 Gbps bandwidth, ensuring that remote signals are updated at the same speed as local I/O.

• IP Address/Station Setting: Configurable via hardware rotary switches or software tools like GX Works3.

• Power Consumption: Low internal power consumption, typically drawing 0.1A to 0.5A from the 24V DC logic supply.

• Connection Medium: Standard RJ45 copper ports or specialized fiber optic connectors for high-noise environments.

Product Advantages

Mitsubishi Couplers provide a strategic advantage in distributed control architectures:

• Radical Wiring Reduction: Instead of running hundreds of wires back to a central cabinet, only a single network cable is required, significantly lowering labor and material costs.

• High Synchronization: Utilizing TSN (Time Sensitive Networking) technology, these couplers allow remote motion control and safety signals to be synchronized with microsecond precision.

• Hot-Swappable Expansion: Many models allow for the replacement of I/O modules on the remote rack without powering down the entire network, minimizing production downtime.

• Integrated Diagnostics: The coupler monitors the health of all attached sub-modules and reports specific fault codes (like wire breakage or short circuits) directly to the main PLC.

• Environmental Resilience: Designed with high vibration resistance and a wide operating temperature range, making them suitable for mounting directly on machinery or in remote terminal boxes.

Product Applications

These couplers are the backbone of distributed intelligence in various industries:

• Large-Scale Assembly Lines: Managing I/O stations spread across a long automotive or battery production line.

• Conveyor and Logistics Systems: Controlling sorters and sensors across a vast warehouse where distance exceeds the limits of standard wiring.

• Water and Waste Management: Linking remote pump stations and flow meters back to a central control room.

• Wind Turbines: Connecting sensors in the nacelle and hub to the main controller at the base of the tower.

• Food Processing: Allowing control electronics to be housed in remote stainless steel enclosures that can withstand wash-down procedures.

Important Precautions

To ensure a stable connection between the coupler and the main controller, observe the following:

• Station Number Duplication: Ensure that the station number or IP address set on the coupler is unique. Duplicate addresses will cause the entire network segment to fail.

• Network Topology Limits: Adhere strictly to the maximum cable lengths and the number of hubs/switches allowed between the PLC and the coupler to prevent signal timing issues.

• External Power Supply: Use a stabilized 24V DC power supply. If the voltage drops due to long wire runs, the coupler may reboot intermittently, leading to "link-up" errors.

• Shielding and Grounding: The communication cable shield must be properly grounded at the coupler to prevent electromagnetic interference from disrupting data packets.

• Module Compatibility: Before adding expansion modules to the coupler, verify the "module version" and "firmware compatibility" to ensure all units can communicate correctly.
