Small Universal Electromagnetic Relay: High-Capacity Switching in a Compact, Dual-Termination Package.

In the intricate world of industrial automation, control panels, and electronic equipment, the electromagnetic relay remains a cornerstone component—responsible for translating low-power control signals into decisive, high-power action. The Small Universal Electromagnetic Relay, offered in 1Z, 2Z, 3Z, and 4Z contact configurations, is engineered to deliver robust switching performance while maintaining a compact footprint. With an impressive 10A contact rating across all configurations, dual termination options (PCB and socket), and a comprehensive range of AC and DC coils, this relay series provides engineers, panel builders, and maintenance professionals with a versatile, reliable, and cost-effective solution for a vast array of switching applications.

High-Capacity Contact Configurations for Demanding Loads

The relay is available in multiple contact arrangements, each designed to meet specific application requirements while maintaining a uniform high current rating.

· 1Z Configuration (SPDT – Single Pole Double Throw): This version features a single changeover contact rated at 10A at 250V AC or 28V DC. It is ideal for straightforward on/off control of medium-power loads such as contactor coils, solenoid valves, small motors, heaters, and lighting circuits.

· 2Z, 3Z, and 4Z Configurations (DPDT, 3PDT, and 4PDT): These variants provide two, three, or four independent changeover contacts respectively, each also rated at 10A at 250V AC or 28V DC. This exceptional circuit density allows a single relay to control multiple loads simultaneously, making them perfect for complex logic interlocking, multi-circuit sequencing, signal routing, and applications where panel space is at a premium.

All configurations feature a low contact resistance of ≤50mΩ (measured at 1A, 6V DC). This low resistance minimizes power loss and heat generation at the contact interface, contributing to long-term reliability and energy efficiency, especially in continuous-duty or high-cycle operations.

Superior Insulation and Dielectric Strength for Safe Operation

Safety and electrical isolation are paramount in any control system, and this relay is constructed to high standards. It offers an insulation resistance of 500MΩ, ensuring effective isolation between the coil and contacts as well as between independent contact sets. This high resistance prevents leakage currents and maintains signal integrity in sensitive electronic environments.

The dielectric strength ratings further demonstrate its industrial-grade robustness:

· Between Coil and Contacts (BCC): Withstands 1500V AC for 1 minute, guaranteeing safe separation between the low-voltage control circuit and the switched load circuit.

· Between Open Contacts (BOC): Withstands 1000V AC for 1 minute, ensuring that contacts can safely interrupt the circuit without arcing or breakdown when in the open state.

· Between Contact Sets (COC): Withstands 1500V AC for 1 minute, providing excellent isolation between independent contact groups in multi-pole configurations.

These rigorous dielectric ratings make the relay suitable for use in applications demanding reliable isolation, including industrial control panels, HVAC systems, safety circuits, and equipment subject to electrical noise.

Optimized Operating Times for Responsive Control

In time-critical applications, switching speed directly affects system performance. This relay delivers dependable timing with an operate time of 25ms and a release time of 25ms. The symmetrical 25ms operate/release times ensure predictable behavior in sequencing applications, minimize arcing during contact transition, and contribute to overall system efficiency. This balanced timing provides positive, snap-action switching while maintaining consistent behavior across millions of operations.

Dual Termination Options: PCB and Socket for Maximum Flexibility

A standout feature of this relay series is its support for both PCB and socket termination. This dual-option design offers significant practical advantages:

· PCB Termination: Allows direct soldering onto printed circuit boards, ideal for high-volume manufacturing, space-constrained designs, and permanent installations where cost and size are critical.

· Socket Termination: Enables plug-and-play installation on standard relay sockets, facilitating easy replacement during maintenance, simplifying field wiring, and reducing downtime. Sockets can be DIN-rail or panel mounted, providing flexibility in control cabinet layout.

This versatility means a single relay model can serve both OEM equipment manufacturers and field service applications, simplifying inventory management.

Low Coil Power Consumption for Energy Efficiency

The relay is designed with energy efficiency in mind. DC coil versions consume just 0.9W nominal power, while AC coil versions consume 1.2VA. This low power burden minimizes heat generation within enclosures and reduces the load on control circuits, making the relay suitable for battery-backed or energy-sensitive applications.

Extensive Coil Voltage Options for Global Compatibility

The relay series offers a comprehensive selection of coil voltages, covering both DC and AC requirements for worldwide deployment.

DC Coil Versions are available in 5V, 6V, 12V, 24V, 48V, and 110V DC. Each is specified with precise pull-in and release voltages (e.g., 4.0V/0.50V for the 5V coil), ensuring reliable operation within defined tolerances. Coil resistance values are held to ±10% tolerance, ranging from 30Ω (5V) to 12,100Ω (110V). The low 0.9W power consumption makes these coils ideal for PLC outputs, microcontroller-driven circuits, and battery-powered systems.

AC Coil Versions cover 6V, 12V, 24V, 48V, 110V, and 220/240V AC. The 110V coil has a resistance of 3,500Ω, while the 220/240V version is offered with two resistance values (14,000Ω for 220V and 16,500Ω for 240V), accommodating variations in global supply voltages. Pull-in and release voltages (e.g., 176V/66V for the 240V coil) guarantee consistent switching across the entire AC voltage range. The 1.2VA nominal power ensures compatibility with low-power control circuits and energy-efficient system designs.

Durable Construction for Long Service Life

While specific mechanical and electrical life figures are not detailed in the provided parameters, the relay is constructed with high-quality materials to withstand millions of operations in typical industrial environments. Contact materials are selected to resist welding and erosion, and the coil insulation system is designed for continuous duty. The dual termination options also contribute to application flexibility without compromising durability.

Wide Range of Applications

The versatility of this relay makes it suitable for countless applications:

· Industrial Control Panels: Interfacing between PLCs and field devices such as contactors, valves, and indicators.

· HVAC Systems: Controlling fans, pumps, compressors, and damper actuators.

· Home Appliances: Providing reliable switching in washing machines, refrigerators, and air conditioners.

· Building Automation: Managing lighting circuits, access control, and security systems.

· Test and Measurement Equipment: Routing signals and switching loads in automated test systems.

· Medical Devices: Offering dependable isolation and switching in diagnostic and therapeutic equipment.
