Small Universal Electromagnetic Relay

The Compact Powerhouse for Versatile Switching Applications

In the intricate world of industrial control systems, automation equipment, and electronic device manufacturing, the humble electromagnetic relay remains an indispensable component. It serves as the critical interface between low-power control signals and high-power loads, enabling safe and reliable switching operations across countless applications. The Small Universal Electromagnetic Relay, available in both 2Z and 4Z contact configurations, represents the perfect synthesis of compact design, robust performance, and exceptional versatility. Engineered to meet the demanding requirements of modern control panels, PCB assemblies, and socket-based installations, this relay series provides engineers and system integrators with a reliable, cost-effective solution for a vast array of switching tasks. Its comprehensive range of coil voltage options, impressive contact ratings, and durable construction make it a truly universal component suitable for global deployment in diverse industries.

Exceptional Contact Performance for Diverse Load Requirements

The relay's core functionality is defined by its contact system, which is engineered to handle a wide spectrum of electrical loads with consistent reliability. Available in two contact configurations, it offers tailored solutions for different application needs:

· 2Z Configuration (DPDT – Double Pole Double Throw): This version features two independent changeover contacts, each rated for an impressive 10A at 220V AC or 30V DC. This high current capacity makes it ideal for directly switching substantial loads such as small motors, solenoid valves, contactor coils, heating elements, and lighting circuits. The robust 10A rating ensures reliable performance even in demanding industrial applications where inrush currents can be significant.

· 4Z Configuration (4PDT – Four Pole Double Throw): This variant provides four independent changeover contacts, each rated for 5A at 220V AC or 30V DC (125V AC). The 4Z model is perfect for applications requiring multiple circuit switching from a single control signal, such as complex logic control, multi-circuit sequencing, or interfacing between different voltage systems. Its compact form factor delivers exceptional circuit density, saving valuable PCB or panel space.

Both configurations feature a low contact resistance of ≤50mΩ (measured at 1A, 6V DC), ensuring minimal power loss and heat generation at the contact interface. This low resistance contributes to long-term reliability and energy efficiency, particularly in continuous-duty applications.

Superior Electrical Isolation and Dielectric Strength

Safety and reliability are paramount in any electrical installation, and this relay excels with its robust insulation characteristics. It offers an exceptional insulation resistance of 500MΩ at 500V DC, guaranteeing effective isolation between coil and contacts, as well as between adjacent contact sets. This high insulation resistance prevents leakage currents and ensures safe operation in sensitive electronic environments.

The dielectric strength specifications further demonstrate its industrial-grade construction:

· Between Coil and Contacts (BCC): Withstands 1500V AC for 1 minute, ensuring safe separation between the control circuit and the switched load circuit.
· Between Open Contacts (BOC): Withstands 1000V AC for 1 minute, guaranteeing that contacts can safely interrupt the circuit without risk of arcing or breakdown when open.
· Between Contact Sets (CCC): Withstands 1500V AC for 1 minute, providing excellent isolation between independent switching channels in the 2Z and 4Z configurations.

These rigorous dielectric ratings make the relay suitable for use in applications requiring reinforced insulation, including medical equipment, industrial machinery, and safety-critical control systems.

Fast and Reliable Operation with Optimized Timing

In time-sensitive applications, switching speed can be critical. This relay delivers consistent performance with an operate time of just 25ms and an equally fast release time of 25ms. This rapid response ensures precise timing in sequencing applications, minimizes arcing during switching, and contributes to overall system efficiency. The consistent timing across both pull-in and drop-out operations allows designers to rely on predictable behavior in their control logic.

Comprehensive Coil Voltage Range for Global Compatibility

A standout feature of this relay series is its extensive selection of coil voltage options, covering both DC and AC requirements for worldwide deployment. This versatility eliminates the need for multiple relay types in inventory, simplifying procurement and reducing costs.

DC Coil Versions are available in standard voltages: 5V, 6V, 12V, 24V, 48V, and 110V DC. Each features precisely defined pull-in and release voltages, ensuring reliable operation within specified tolerances. The coil resistance values (ranging from 30Ω for 5V to 12,100Ω for 110V) are controlled to within ±10%, providing consistent performance across production batches. The nominal coil power is a modest 0.9W, minimizing the burden on control circuits and reducing heat generation within enclosures.

AC Coil Versions cover common mains voltages: 6V, 12V, 24V, 48V, 120V, and 220/240V AC. The 220/240V option includes two resistance values (14,000Ω for 220V and 16,500Ω for 240V), accommodating variations in global supply voltages. AC coil versions feature a low nominal power consumption of just 1.2VA, ensuring compatibility with low-power control circuits and energy-efficient system designs. The carefully calibrated pull-in and release voltages guarantee consistent switching behavior across the entire AC voltage range.

Flexible Termination Options for Design Freedom

Understanding that different applications demand different mounting solutions, this relay series offers both PCB and socket termination options. The PCB terminals allow for direct soldering onto printed circuit boards, ideal for high-volume manufacturing and space-constrained designs. Alternatively, the socket-mount option enables easy installation on standard relay sockets, facilitating quick replacement during maintenance and allowing for panel-mounted configurations. This dual-termination flexibility makes the relay equally suitable for OEM equipment manufacturing and field-installed control panels.

Compact Dimensions with Industrial-Grade Durability

Despite its impressive contact ratings and multiple pole configurations, the relay maintains a compact footprint suitable for high-density installations. Its design prioritizes long-term reliability, with materials and construction chosen to withstand millions of operations in demanding environments. The clear terminal markings and standardized pin configurations simplify wiring and reduce installation errors.

Ideal for a Wide Spectrum of Applications

The versatility of this relay makes it an ideal choice for countless applications across industries:

· Industrial Control Panels: Interfacing between PLCs and field devices such as motors, valves, and contactors.
· HVAC Systems: Controlling fans, pumps, compressors, and damper actuators.
· Automation and Robotics: Switching solenoids, actuators, and indicator lights in automated machinery.
· Building Management: Controlling lighting circuits, access control systems, and security equipment.
· Medical Devices: Providing reliable switching in diagnostic and therapeutic equipment where safety is paramount.
· Telecommunications: Switching backup power systems, signal routing, and equipment control.
· Test and Measurement Equipment: Routing signals and switching loads in automated test systems.
