Relay 704

Product catalog summary
Description: The Relay 704 is a polarized latching relay featuring a position display and manual operation switch. It utilizes the H-armature principle, providing high resistance to shocks and vibrations, ensuring a defined switching position without information loss during power failures. The relay operates with a pulse-driven mechanism, minimizing coil heating, and can be manually set.
Standards Compliance: The relay is designed according to IEC 61810 part 1/VDE 0435 part 201 and meets the overload and short circuit requirements of IEC 62053/62054.
Technical Data:
  • Coil Data: Rated voltage ranges from 6 to 48 VDC, with a rated power of 3.0 W and operating power to set at 2.0 W. The pulse to set is 20 ms, with an action time of less than 15 ms.
  • Contact Data: Maximum contact arrangement is 1 normally open (1a), with contact material AgSnO2. Maximum switching power is 10,000 VA / 15,000 VA, maximum switching voltage is 440 VAC, and maximum switching current is 40 A / 60 A. The mechanical life is 106 operations.
  • Insulation: Creepage and clearance distance between coil and contact is 8 mm, with a test voltage of 4,000 V eff. Dielectric strength between coil and contact is 12 kV / 1.2 / 50 µs.
  • General Data: The relay operates within an ambient temperature range of -40 to +70 °C and weighs 36 g. It conforms to VDE, UL, CSA, SEV, and SEMKO standards.
Soldering Advice: The relay is dust-protected, and care should be taken to prevent flux medium and lead-tin evaporations from entering the relay during soldering.
Identification and Ordering: The relay can be ordered using identification codes, with options for different dimensions and contact materials. Standard windings are available, with the relay coil capable of double or single winding operation.
Technical Drawings: Detailed technical drawings are provided for various configurations (704 M, 704 Q, 704 V, 704 VR) to assist in installation and integration.

Relay 704-1

Technical Data Polarized latching relay, with position display and switch Using the H-armature principle the polarised latching relays are noted for their high resistance to shocks and vibrations. They are always in a defined switching-posi- tion and therefore there is no loss of information in case of power failure. The advantage of polarised latching relays is the pulse driven operation of some milliseconds, coil heating can be neglected. Relay can also be set by manual operation. The relays are designed and manufactured in accordance to international Standards of IEC 61810 part 1/VDE 0435 part 201 as well as they meet overload and short circuit Technical data Coil data Rated voltage 6-48 VDC Test voltage contact - contact open contact coil - contact General data Ambient temperature -40 ...+70 °C
