PRODUCT PERFORMANCE​

Adopts 10 sets of high-density changeover contacts configuration, supporting synchronous switching of multi-circuit signals and high-power load driving, adapting to complex core control links, improving system integration density and control flexibility​

High-conductivity silver alloy (AgSnO₂) contact material combined with fully sealed structure, mechanical life over 15 million cycles and electrical life over 200,000 cycles, meeting the long-term stable operation requirements in high-frequency and high-load scenarios​

6000Vac ultra-high electrical isolation between coil and contacts, 3000Vac isolation between contact groups, effectively resisting strong electromagnetic interference and high-voltage surges in industrial sites, ensuring the integrity of core control signal transmission​

Industrial-grade wide-temperature and wide-humidity adaptability, can work stably in the temperature range of -40℃ to 75℃ and 5%-95% non-condensing humidity environment, adapting to extreme working conditions such as alpine, high temperature and high humidity​

24VDC wide-range control voltage input design, compatible with power supply fluctuations in industrial sites, dual surge-resistant coil protection can resist instantaneous voltage impact and avoid module damage​

Dual installation methods for flexible adaptation, both standard 3U rack integration and independent DIN rail fixing are available, meeting the different installation needs of core control cabinets and distributed control nodes​

Built-in contact wear warning and circuit short circuit/overload detection functions, combined with a comprehensive self-diagnostic mechanism, fault location is accurate to a single contact, greatly reducing the operation and maintenance cost and downtime of core systems​

Flame-retardant ABS+glass fiber reinforced housing and fully sealed design, dustproof, moisture-proof, corrosion-resistant and anti-aging, adapting to harsh environments such as high dust and strong corrosion in industrial sites​

Extremely fast action response, pick-up time ≤10ms and drop-out time ≤7ms, meeting the millisecond-level switching needs of core control circuits and ensuring real-time and accurate execution of control commands​

Seamlessly compatible with ALSTOM’s full range of core control systems, no additional adaptation modules required, low control link delay, ensuring high reliability of core industrial processes and rail transit systems​
