Products that are marked "On Order" in the "Available Quantity" column are usually not in stock. Such products are available for purchase, however, due to their limited customer base, they usually have higher minimum quantities. DACPOL offers products that are not in stock for the following reasons: DACPOL currently has a large number of electronic components in stock and adds new products every day, however, tens of thousands of additional components and their various variants are available from our suppliers. Even though it is unreasonable to have all these products in stock due to the limited sales, we believe that it is in the best interest of our customers to make them available. Our goal is to inform customers about the maximum number of products available and enable them to make decisions based on specifications, prices, availability, required minimums and our technical advice. Please note that selecting the "In Stock" checkbox may limit the display to only products available for delivery straight from the shelf.

What is a single-phase solid-state relay?

Also called electronic or SSR (Solid State Relay), it is the electronic equivalent of electromechanical relays – built from semiconductor components such as transistors, thyristors, or triacs. These relays are logic circuits for switching voltages, currents, and frequencies.

We distinguish two main types of relays: electromechanical relays and solid-state relays.

The function of relays, whether electromechanical or solid-state SSR, is to control the load (output) circuit using a low-voltage signal from an isolated control (input) circuit.

Solid-state relays – applications.

  • Mainly used in electrical devices and electronics – installed in sockets and printed circuits.
  • They are used, among other things, to separate electrical potentials (galvanic isolation) – this protects the control plane, e.g., from malfunctions caused by transient states or interference currents.
  • Another application is signal processing and switching amplification, used when current and voltage exceed the rated value of the optoelectronic transistor.

We offer professional assistance in selecting the right products not only from the single-phase relay category but also across our entire range. We also provide professional technical advice for finding the appropriate solutions. Upon customer request, we strive to tailor the offer and adapt products to the type of facility or working conditions.

All products come from trusted and reputable suppliers, so using the devices we offer significantly increases safety and work efficiency and ensures long-lasting installation durability.

Using our products enhances reliability and work safety.
