Semiconductor Relays/Contactors From DOLD

  • Solid-state contactors proved to be good in industrial applications where high switching frequencies or high switching cycles are required. With their long service life and wearless switching they solve switching and control tasks in specific applications in an extremely economic manner. Application areas include:
  • Extrusion and injection moulding plants
  • Heating controls
  • Soldering lines
  • Hot-melt glueing robots
  • Oven controls
  • Three-phase motors
  • Lighting controls
  • Materials handling installations
  • Dispensing equipment
  • Packaging machines
  • Automats
  • Copying equipment
  • Pumps
  • Self-service automats
  • Traffic lights
  • ... and many more

Advantages

  • Ready-to-use products and easy installation:
    Snap on - Wire - Done
  • Long service life
  • Long service life
    Noiseless switching
    thanks to the use of semiconductors instead of electromechanical contacts
  • Excellent EMC properties
    because of zero-voltage switching
  • Innovative technology
    DCB technology optimizes heat dissipation
  • Low space requirements
    thanks to compact design and optionally up to 3 separately triggerable solid-state contactors within a single housing
  • Customer-specific solutions and special-purpose variants
    e.g. with finely adjustable load circuit monitoring or with analog input for burst firing control for temperature controllers for cartridge-type heaters and other heating equiment
  • Suited for high switching frequencies
  • Low trigger current
    only 5 mA
  • Rough environmental conditions
  • High I²t
    therefore no extra solid-state fuse needed

Technology

DOLD semiconductior contactors and relays dead easily to handle

Ready-to-use products for your applications

With optimized parameters such as heat sink size, EMC, heat dissipation etc. To select the product which is best suited for your application it is enough to know the current flowing through your load.

Quick and easy installation

Simply snap these ready-to-use products on the top hat rail or screw them directly on the mounting plate.

Innovative technology

Switching of high load currents results in considerable heating of semiconductior contactors and relays. Inacceptable temperature rises may cause device failures after a time. To counteract this risk DOLD developed advanced technologies. Thanks to the DCB (Direct Copper Bonding) method it is possible to optimize heat dissipation in the power output element of the semiconductior contactors and relays and to ensure the operational reliability of your systems.
