Depending on the requirements, the choice between
electromechanical and solid-state relays is made based on
the different advantages that the different versions offer:
Advantages of solid-state relays (SSR)
• Longer service life and increased reliability
No moving parts or wear on the contacts
• Small dimensions
Saves space on the PCB and mounting rail
• Low control power
An LED is activated - no mechanical parts are moved
• Fast response times
Fast switching, which allows high
frequencies to be achieved
• No contact bounce
Reduces switching delays
• No switching noise
Suitable for use in noise-sensitive environments
• Not susceptible to shock and vibration
Prevents unwanted switching statuses
• No electromagnetic radiation due to switching sparks or
coils
No interference of adjacent assemblies
or electronics components
