22 Series Relays

Product catalog summary

Technical Data and Specifications
The 22 Series Relays are compact, environmentally friendly devices compliant with RoHS directives. They feature a non-polarized LED indicator and high switching power, with approvals from UL, CE, RoHS, CCC, and Demko. The relays are designed for overvoltage category III as per EN IEC 60947-5-1 standards.

Electrical Characteristics
AC and DC coil ratings are provided with specific voltage, resistance, and current values. The relays offer excellent electrical and mechanical durability, with AC coils rated for 30 million operations and DC coils for 50 million. They have a dielectric strength of 5,000V AC between contact and coil.

Model Number Structure and Selection
The relays are available in SPDT and DPDT configurations with various voltage options (12V, 24V, 110V, 230V). Model numbers are structured to indicate type, voltage, and additional features like LED or diode.

Accessories
Accessories include mounting clips and DIN rails, with specifications for dimensions and materials. The relays can be mounted using DIN rails or M3 screws.

Protection and Safety Precautions
Protection circuits are recommended to prevent contact welding and ensure safe operation. Safety precautions include avoiding strong magnetic fields, ensuring proper coil voltage, and using appropriate wire sizes. The relays should not be used in environments with dust or corrosive gases.

Application Considerations and Warranty
WERNER provides a one-year warranty against defects in materials and workmanship. The company is not responsible for misuse or improper installation. Product specifications may change without notice, and users are advised to consult WERNER representatives for confirmation of specifications and approvals.

22 Series Relays Instructions Apply rated voltage to the relay coil to ensure correct relay type. When using a power supply containing a ripple voltage, suppress the ripple factor within 6% however, a complete DC voltage is best for the coil power to make sure of stable relay operation. Pickup voltage and dropout voltage depend on the ripple factor when power is supplied through a rectification circuit. Include a smoothing capacitor for better operation. vr-T^i i t Emin Emax Emean DC Emean Emax = Maximum of pulsating current Emin = Minimum of pulsating current Emean= DC mean value Special consideration...

22 Series Relays Safety Precautions Ÿ Ÿ Ÿ Ÿ Ÿ Ÿ Ÿ Ÿ Ÿ Do not drop, shock or remove the relay cover to maintain the initial characteristics. The relay cover should not be removed from the base during normal operation. Use the relay in environments free from dust, condensation, dioxide or hydrogen sulfide. Make sure that the coil voltage does not exceed applicable coil voltage range. Prevent usage of relays in the vicinity of strong magnetic field, as that may cause in malfunctioning of relays. Failure to turn off power before wiring, installation, removal and maintenance may cause electrical shock...
