The ABB XV5628A is a robust electromechanical control relay from ABB’s trusted XV series, engineered for reliable switching of industrial loads in automation and power control applications. Featuring a 24V DC coil and single-pole double-throw (SPDT or 1CO) contact configuration, the ABB XV5628A delivers dependable performance in PLC output modules, motor starters, safety interlocks, and signal isolation circuits. Designed for use with standard plug-in sockets (e.g., XV5901 or XV5902 series), it supports rapid replacement without rewiring—minimizing production downtime during maintenance.
Built with silver alloy contacts and a durable thermoplastic housing, the ABB XV5628A handles up to 10A at 250V AC or 30V DC, with high surge current tolerance for inductive loads like solenoids and contactor coils. An integrated LED indicator provides immediate visual confirmation of coil energization, aiding diagnostics in complex control panels. The ABB XV5628A meets international standards including IEC 61810 and carries CE certification, ensuring compatibility across global manufacturing and process environments—from food and beverage lines to heavy machinery.

Main Features and Advantages
Reliable Switching for Inductive Loads: The ABB XV5628A is specifically designed to handle the high inrush currents and back-EMF generated by solenoids, relays, and small contactors. Its robust contact gap and arc suppression ensure long service life even under frequent switching—critical in packaging machines or automated assembly lines.
Visual Diagnostics with Integrated LED: Unlike basic relays, the ABB XV5628A includes a built-in green LED that illuminates when the coil is energized. This allows technicians to instantly verify control signals from PLCs or timers without probing live circuits—enhancing safety and speeding up troubleshooting.
Universal Socket Compatibility and Easy Replacement: The ABB XV5628A uses ABB’s standardized pin layout, making it fully compatible with the XV5900-series sockets, which can be mounted directly on DIN rails or panel surfaces. The relay locks securely into place yet can be removed by hand—no tools required—enabling fast swaps during failures or upgrades.
Compact Design with High Performance: Despite its small footprint (approx. 22.5 mm wide), the ABB XV5628A delivers industrial-grade performance with 10A switching capacity and 4 kV insulation. This density allows more relays per cabinet, reducing panel size and cost while maintaining separation between control and power circuits.
Application Field
The ABB XV5628A is widely deployed in industrial control panels where reliable, isolated switching of medium-power loads is required. In packaging and bottling lines, it interfaces between PLC digital outputs and pneumatic valve manifolds, enabling precise actuation of fillers, cappers, and labelers. Within HVAC and building automation systems, the ABB XV5628A controls fan contactors, damper actuators, and alarm buzzers—benefiting from its quiet operation and long electrical life.
In material handling and conveyor systems, the relay isolates safety light curtains or emergency stop circuits from main drive controls, providing fail-safe disconnection. It is also common in machine tool control cabinets, where it decouples CNC logic from coolant pumps or tool changers. Additionally, system integrators use the ABB XV5628A in water treatment plants to switch chemical dosing pumps and in renewable energy skids (e.g., solar tracker controllers) due to its wide temperature tolerance and resistance to voltage fluctuations. Its compliance with IEC standards ensures acceptance in both European and North American installations.

Installation and Maintenance
Pre-installation preparation: Before installing the ABB XV5628A, confirm that the selected socket (e.g., XV5901 or XV5902) matches the pin configuration and mounting style (panel or DIN rail). Ensure the coil voltage (24V DC) aligns with the control circuit supply, and verify polarity if the socket includes diode protection. Use stranded wires with ferrules for secure terminal connections, and avoid exceeding 10A per contact under continuous load conditions.
Maintenance recommendations: The ABB XV5628A requires no routine maintenance but should be inspected periodically in high-cycle applications. Listen for abnormal clicking or chattering, which may indicate coil voltage drop or contact wear. If the LED is on but the load isn’t switching, the contacts may be welded or eroded—replace the relay immediately. Always de-energize the control circuit before removal. Store spare ABB XV5628A units in dry, static-free environments to preserve coil insulation and contact integrity over time.
