Safety Requirements
Relays with forcibly guided contacts are essential for safety applications, ensuring decoupling of voltage potentials and enabling self-monitoring systems. They must maintain a minimum contact gap of 0.5 mm in case of faults.

Strengths and Customer Value
ELESTA's relays support switching currents from 5mA to 16A, offer high insulation values, and are RoHS compliant. The company prioritizes customer service with rapid support and short delivery times.

Technical Data and Standards
Relays are designed with double or reinforced insulation, high mechanical life expectancy, and compliance with international standards such as UL and TÜV. They are suitable for continuous duty and have a wide excitation voltage range.

Specifications
The relays are designed to operate in ambient temperatures from -40°C to +70°C, with a weight of approximately 20g. They feature vibration and shock resistance, and are suitable for various mounting positions.

Electrical Characteristics
The relays support a maximum switching capacity of 250VAC at 6A for AC1 applications and 24VDC at 6A for DC1 applications, with a contact lifetime of approximately 100,000 operations.

Insulation and Safety
Relays provide basic and double or reinforced insulation, complying with safety standards like IEC 60664-1 and UL 94 / V0 for fire protection.

Approvals and Standards
Approved by SEV, UL, cUL, and TÜV, the relays meet EN 50205 standards and are suitable for railway applications as per EN 50155.

Mechanical and Thermal Properties
Relays have a mechanical life of over 10 million operations, a switching frequency of 15Hz, and a thermal resistance of 55K/W.

Ordering Information
Details on ordering include the number of NO and NC contacts, type designation, and coil voltage.

Environmental and Physical Characteristics
Relays are resistant to short circuiting, have a pollution degree of 2, and overvoltage category III.

Recommendations and Best Practices
Guidelines include avoiding damaged gold layers for signal circuits and managing heat accumulation from other components.

Diagrams and Graphs
Diagrams illustrate circuit layouts and load limit curves for direct current, showing operational capabilities and limitations.

Environmental Compliance
