Advanced universal marshalling for critical industrial applications

The X1 Series from G.M. International is an advanced universal marshalling system engineered for hazardous areas and high-integrity SIL applications. Designed for upstream, midstream, and downstream facilities, the X1 Series combines space efficiency, functional safety, and seamless system integration in complex industrial automation environments

Universal marshalling for hazardous areas

Oil refineries, gas processing plants, offshore platforms, and petrochemical facilities require reliable interface modules capable of operating in extreme temperatures and classified areas.

The X1 Series offers a complete portfolio of pass-through modules, galvanic isolators, signal conditioners, relays, and intrinsically safe modules. Supporting both analog and digital field signals, it ensures seamless interfacing between DCS, PLC, and field instrumentation systems.

Fully compatible with intrinsically safe loops, the system can be safely installed in Zone 2 / Div 2 hazardous areas, making it ideal for oil & gas installations where safety compliance and operational continuity are critical.

SIL 2 / SIL 3 certified functional safety

Certified to SIL 2 and SIL 3 in accordance with IEC 61508, the X1 Series meets the highest functional safety requirements for emergency shutdown systems (ESD), fire & gas systems, and critical process control applications.

Its fail-safe architecture includes mechanical polarisation keys that prevent incorrect module insertion, reducing human error in high-risk environments. The integrated gateway automatically identifies each module’s unique ID and configuration parameters, enhancing diagnostics, traceability, and overall system integrity.

Compact Design for Space-Constrained Control Rooms

Control rooms and marshalling cabinets in oil and gas facilities often operate under strict space constraints. The compact board design of the X1 Series significantly reduces cabinet footprint, lowering installation, wiring, and maintenance costs.

Configurable 8- or 16-channel I/O cards enable tailored solutions for project-specific requirements while maintaining spare channel capacity for future expansion, an important advantage for long-term industrial infrastructure projects.

Built for extreme industrial conditions

Designed to operate from -40°C to +70°C, the X1 Series withstands harsh industrial environments typical of onshore and offshore installations. Its IP20-rated housing, DIN rail TS35 mounting, visible LED diagnostics, and maintenance position allowing field device checks without cabinet unwiring improve reliability and operational efficiency.

For operators seeking a SIL 3 universal marshalling solution for hazardous areas, the X1 Series delivers a robust, scalable, and future-ready interface platform for the global oil & gas industry.
