Next generation of safetyX1 Series X1 Series is a complete range of interfaces for universal marshalling within limited spaces: pass-through, galvanic isolators, converters, relays and intrinsically safe modules. Specifically designed for high risk industries, challenging functional safety (SIL) requirements and harsh environmental conditions. The Series requires less maintenance and installation efforts on site, with a smaller cabinet footprint and more flexibility for spare channels. STRENGTHS • Reduced footprint: high density design, 10 mm per channel • Universal application flexibility: support...

X1 Series Structure Retention and detachment leverage mechanism LEDs for power, status and fault indication are visible through the transparent cover Laser engraving on module enclosure provides permanent marking of IS parameters, certifications and instructions Mechanical polarization key system avoids misplacing and potentially destructive insertion of low-voltage modules into high-voltage slots and NIS modules into IS slots High thermal efficiency: - 40 / +70°C extended operating range Extractable screw or spring field terminal blocks Redundant and protected 24 Vdc power supply High grade...

Terminal blocks Fail-proof architecture Polarization keys ensure correct insertion on each module on the board, therefore preventing dangerous misplacements. The gateway is able to identify each module’s unique ID and characteristics (AI, AO, DI, DO, Relay, Pass-through). Fully redundant on-board 24Vdc power supply. Functional safety is achieved on all modules via SIL3 and SIL2 certifications according to IEC61508, ensuring the highest levels of reliability and system uptime. SMART FEATURES FULL COMPABILITY • A single remote access point allows for identification, configuration, monitoring and...
