M Series I/O Bus Extension Module (Head)
Part Number: MRGH
- Flexible Expansion: Scale up to 6 rows (6 sections) with support for a total of 64 local I/O expansion modules
- Streamlined Installation: Installs to the right of the power module in expansion sections (from the second row onward). Features a single front port—requiring an MRGT module to bridge connections to subsequent rows.
The Fatek M series combines advanced technology, flexible configuration and exceptional computing and motion control capabilities.
With high stability and outstanding performance, it is widely used in 3C manufacturing, food processing, coating technology, packaging and box stapling, textiles, and many other industries.
FATEK HARD PLC runs control tasks directly in hardware—no OS boot time required. The moment power is on, it’s ready for I/O monitoring, processing, and communication. In contrast, PC-like Soft PLC systems rely on complex operating
systems, often taking 10 to 30+ seconds to boot—during which no control or monitoring is possible.
FATEK HARD PLC hardware architecture delivers 5x higher efficiency than Soft PLCs with 80% reduced computation time for identical tasks. This breakthrough enhances system responsiveness and empowers complex, large-scale control applications with ultra-stable and high-efficiency automation solutions.
Backed by 30+ years of PLC expertise, FATEK’s HARD PLC technology integrates the control core into a single chip. Through continuous architecture refinement, it achieves industry-leading performance with minimal components and ultra-low power consumption. Its efficient and streamlined design keeps heat and power usage exceptionally low, even at high processing speeds—reducing heat generation by up to 58% compared to Soft PLC. Lower temperatures ensure longer component lifespan and higher system reliability.
Ultimate speed leading ahead of the industry innovatively developed high-performance processor and high-performance algorithm. Up to 0.8ns for the command processing speed. Pushes the control performance to the unimaginable “ns” realm. Advanced & Ultra-precise Motion Control Built-in advanced motion control functions including E-Cam, helix interpolation, ICF/ICA*, etc. Equipped with a dedicated motion control chip that independently processes motion control tasks. Even for complex and large motion control commands, they can be executed instantly and accurately without affecting the PLC scan cycle. Ultra-low interrupt latency With a 3µs industry-leading ultra-low interrupt latency, ensures precise execution for control demands requiring fast reactions and ultra-low latency, completely unaffected by program complexity or PLC scan cycle time.
Versatile models for diverse scenarios MQ, MA, MU, MS, and ME: multiple versatile models from PLC control to advanced multi-axis motion control.
From small I/O points to comprehensive factory-wide control solutions with tens of thousands of points* delivering versatile and flexible solutions tailored to your needs.
Built-in EtherCAT/Ethernet dual interfaces EtherCAT connects seamlessly with 3rd-party EtherCAT servos. Motion and positioning control without extra modules. Ethernet supports Modbus TCP, MQTT and user-defined protocols. Easy data exchange with devices, systems and platforms.
IoT control hub – Supports FATEK IoT solution without the need of fixed IP and IoT gateway. Easily achieve applications such as remote monitoring, project maintenance and alarm notification. Also supports the MQTT Protocol for interfacing with the third-party cloud platforms.
| Part Number | MRGH |
| Product Type | Head Branch Expansion Module |
| Number of Expansion | It can be expanded up to 6 rows (6 sections) with a total of 64 local IO expansion modules |
| Maximum Expansion Distance | Single section of 2 meters, total length 10 meters (Used with MFB20M-120 cable) |
| Installation Location | It can only be installed to the right of the power module, not in the main section, and must be placed in the expansion section (from the second row onward). There is only one port on the front, so it cannot be directly daisy-chained to the next row’s MRGH. To connect to the next row, an additional MRGT module is required. |
| Power Expansion | The left side must be connected to a power module or supplied with 24V from an external power source to provide power for the expansion modules in this section. |
| Notes | Requires the use of MFB20M-120 dedicated connection cable and includes one MRE end module. |
