Product details
Weidmüller's 990874 represents a breakthrough in Terminal Blocks - Interface Modules design for railway signaling systems. Developed to meet EN 50155 standards, this robust interface module ensures fail-safe operation in critical train control applications.The Terminal Blocks - Screw Connection system incorporates vibration-resistant contacts that maintain reliable connections despite constant shock and vibration in rail vehicles.Featuring Rectangular, Male interfaces, the module provides galvanic isolation between different voltage domains in train control systems.The Latches includes flame-retardant materials that meet stringent railway safety standards for tunnel applications.With 32 options, the solution scales from simple door control interfaces to complex train management system connections.The Fuses implementation includes shock and vibration resistance, EMI shielding, and maintenance-friendly design for rapid depot servicing.Rated for 120VAC, 24VDC operation, the insulation system withstands transient overvoltages common in railway power distribution networks.The 2 A capacity ensures reliable operation of both low-current signaling circuits and high-power traction system controls.The 0°C ~ 50°C range certification includes full functionality in both arctic winter conditions and desert summer environments.The 4.606" (117.00mm) form factor meets strict space constraints in rolling stock while maintaining adequate clearance for high-voltage isolation.Designed with 4.291" (108.99mm) spacing, the module prevents creepage and clearance issues in humid railway tunnel environments.Compatible with 14-26 AWG conductors, the termination system accommodates both flexible train wiring and fixed installation cables.
