Why choose this product?

• Proven signal relay design with DPDT (2c) contacts
• Parameters suitable for precise and low-energy control applications
• Defined switching limits for both AC and DC loads including a maximum switching voltage of 125 V

Installation and operating instructions

• When designing, consider the type of load (resistive/inductive) and use appropriate protective elements (e.g. RC element, diode, varistor) to limit overvoltage
• Observe the nominal coil voltage of 12 V DC and ensure a stable power supply including correct polarity if relevant to your wiring
• For long-term reliability, do not exceed the maximum switching voltage and current and verify temperature rise under real-world conditions.

Safety notice

• The relay can switch voltages up to 125 V AC/DC; working with dangerous voltages requires professional competence and compliance with applicable standards
• Before handling, disconnect the device from the power supply and verify that there is no voltage.
• Ensure sufficient insulation distances and shielding according to the specific application
