Relay Modules

Semiconductors relays / contactors

  • 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
  • Copying equipment
  • Self-service automats
  • Traffic lights

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

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.
