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 AC semiconductor relay?

Single-phase AC semiconductor relay, or SSR, has no moving parts and uses the electrical and optical properties of solid state semiconductors to perform its input to output isolation and switching functions. Solid state relays can be designed to switch both AC or DC currents, by using an SCR, TRIAC, or switching transistor output instead of the usual mechanical normally-open (NO) contacts.

In principle, relays and contactors operate in the same way - contactors are devices for switching power supply circuits, while relays transmits a low-voltage signal or signal with a zero potential. The contactors are connected to electrical devices such as electric motors, while relays are used to provide control signals, e.g. to or from PLCs.

Contactor-relay systems are called systems in which the contactors are executive elements (they turn on and off the appropriate working circuits at the right moment), while relays control the operation of contactors causing the coils of contactors to be charged depending on specific factors.

Applications:

The most common application of solid state relays is in the switching of an AC load - to control the AC power for ON/OFF switching, light dimming, motor speed control or other such solutions, where power control is needed.

We're offering the highest quality of sold products, regardless of whether they are interface relays, solid state relays or three-phase relays. We also provide technical data on products from the Relays and Contactors section, all complying to the producers’ data, so that our customers can be sure that the chosen article is exactly what they need.

Our offer also includes regulators, control systems, electromechanical relays and large power relays.

Each time we provide professional help in choosing the right product, as well as technical advisory services in searching for proper solutions. We try to adjust each offer to all individual need and requirements stated by the costumer, but also accordingly to the workplace environment and a type of the establishment.

On our website you can familiarize yourself with the full range of goods from the category: Energetics, Electrics, Automation.
