Small Universal Electromagnetic Relay: 2Z and 3Z Socket‑Mount Versatility with Silver Alloy Contacts

In the demanding environments of industrial automation, control panels, and electrical equipment, the electromagnetic relay remains a fundamental component for translating low‑power control signals into reliable switching of higher‑power loads. The Small Universal Electromagnetic Relay, available in 2Z (DPDT) and 3Z (3PDT) contact configurations, is engineered to offer a balanced combination of robust contact performance, excellent electrical isolation, and socket‑mount convenience. Featuring silver alloy contacts, symmetrical 20ms operate/release times, and a wide range of AC and DC coils, this relay series provides engineers, panel builders, and maintenance professionals with a dependable, cost‑effective solution for countless switching applications.

High‑Quality Silver Alloy Contacts for Reliable Switching

A key differentiator of this relay is the use of silver alloy contact material. Silver alloy offers superior conductivity, resistance to arc erosion, and excellent anti‑welding properties, ensuring consistent performance over thousands of switching cycles. This material choice is particularly important when switching inductive loads (such as contactor coils, solenoids, and small motors) where arcing can degrade ordinary contacts. The result is extended electrical life and reduced maintenance.

All contacts exhibit a low contact resistance of ≤50mΩ (measured at 1A, 6V DC), which minimises power loss and heat generation, contributing to overall system efficiency and reliability.

Contact Configurations and Ratings for Varied Loads

The relay is offered in two contact arrangements, each tailored to specific application requirements.

· 2Z Configuration (DPDT – Double Pole Double Throw):

This version provides two independent changeover contacts, each rated at 7.5A at 220V AC or 28V DC. The 7.5A capacity is ideal for switching medium‑power loads such as contactor coils, solenoid valves, small motors, heaters, and lighting circuits. It offers a practical balance between current handling and contact life, making it suitable for a wide range of industrial and commercial applications.
· 3Z Configuration (3PDT – Triple Pole Double Throw):

This variant provides three independent changeover contacts. Contact capacity is rated at 7.5A for normally open (NO) contacts and 5A for normally closed (NC) contacts at 220V AC or 28V DC. The distinction between NO and NC capacities allows designers to optimise circuit layouts, using the higher‑rated NO side for loads that are energised most frequently, while the NC side handles lighter or less critical duties. The 3Z configuration is perfect for applications requiring simultaneous switching of multiple circuits from a single control signal, such as complex logic interlocking, multi‑circuit sequencing, or signal routing in test equipment.

Superior Insulation and Dielectric Strength for Safe Operation

Safety and isolation are paramount in any control system. This relay offers an insulation resistance of 500MΩ at 500V DC, 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 1000Vr.m.s for 1 minute, guaranteeing safe separation between the low‑voltage control circuit and the switched load circuit.
· Between Open Contacts (BOC): Withstands 1500Vr.m.s for 1 minute, ensuring that contacts can safely interrupt the circuit without arcing or breakdown when in the open state.

These rigorous 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.

Symmetrical 20ms Operating Times for Precise Control

In time‑critical applications, switching speed directly affects system performance. This relay delivers consistent timing with an operate time of 20ms and a release time of 20ms. The symmetrical 20ms timing ensures predictable behaviour in sequencing logic, minimises arcing during contact transition, and contributes to overall system responsiveness. This balanced performance is particularly valuable in applications such as conveyor control, pump sequencing, and safety interlocking.

Socket‑Mount Design for Easy Installation and Maintenance

The relay is designed exclusively for socket‑mount termination, using standard relay sockets. This approach offers significant practical advantages:

· Tool‑Free Replacement: When a relay reaches its end of life or fails, it can be unplugged and replaced in seconds without disturbing any field wiring.
· Simplified Panel Assembly: Sockets can be pre‑wired during panel fabrication, with relays installed later, streamlining production and testing.
· Reduced Downtime: Maintenance personnel can quickly swap a suspect relay with a known‑good unit, minimising system downtime.
· Flexible Mounting: Sockets are available for DIN rail or panel mounting, providing versatility in control cabinet layout.

Low Coil Power Consumption for Energy Efficiency

The relay is designed with energy efficiency in mind. DC coil versions consume just 1.5W nominal power, while AC coil versions consume 2.5VA. This low power burden minimises 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 6V, 12V, 24V, 48V, 100V, and 110V DC. Each is specified with precise pull‑in and release voltages (e.g., 4.8V/0.6V for the 6V coil), ensuring reliable operation within defined tolerances. Coil resistance values are held to ±10% tolerance, ranging from 24Ω (6V) to 9,650Ω (110V). The 1.5W power consumption provides adequate magnetic force while remaining suitable for PLC outputs and microcontroller‑driven circuits.

AC Coil Versions cover 6V, 12V, 24V, 48V, 110/120V, and 220/240V AC. The 110/120V coil has a resistance of 1,512Ω, while the 220/240V version is offered with two resistance values (6,050Ω for 220V and 7,200Ω for 240V), accommodating variations in global supply voltages. Pull‑in and release voltages (e.g., 176V/72V for the 240V coil) guarantee consistent switching across the entire AC voltage range. The 2.5VA nominal power ensures compatibility with low‑power control circuits and energy‑efficient system designs.

Durable Construction for Long Service Life

Although specific mechanical and electrical life figures are not detailed in the provided parameters, the relay is constructed with high‑quality materials and proven design practices to withstand millions of operations in typical industrial environments. The silver alloy contacts resist welding and erosion, while the coil insulation system is designed for continuous duty. The socket‑mount design also contributes to longevity by reducing thermal and mechanical stress on the relay terminals during replacement.

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.
· Automation and Machinery: Switching solenoids, actuators, and indicator lights.
· Building Management: Controlling lighting circuits, access control, and security systems.
· Test and Measurement Equipment: Routing signals and switching loads in automated test systems.
· Power Supplies and Battery Systems: Providing isolation and switching in charger circuits and backup power systems.
