Product details
Phoenix Contact's 2281733 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 D-Sub, Male interfaces, the module provides galvanic isolation between different voltage domains in train control systems.The Jackscrew Socket includes flame-retardant materials that meet stringent railway safety standards for tunnel applications.With 37 options, the solution scales from simple door control interfaces to complex train management system connections.The Label Holder implementation includes shock and vibration resistance, EMI shielding, and maintenance-friendly design for rapid depot servicing.Rated for 125V operation, the insulation system withstands transient overvoltages common in railway power distribution networks.The 2.5 A capacity ensures reliable operation of both low-current signaling circuits and high-power traction system controls.The 3.110" (79.00mm) form factor meets strict space constraints in rolling stock while maintaining adequate clearance for high-voltage isolation.Designed with 3.031" (76.99mm) spacing, the module prevents creepage and clearance issues in humid railway tunnel environments.Compatible with 12-24 AWG conductors, the termination system accommodates both flexible train wiring and fixed installation cables.
