Basic Solid State Relays
Basic Solid State Relays
Basic Solid State Relays. The following are examples of home made solid state relays that could be used to replace mechanical types in many model railroad circuits. These Relays would be ideal for applications where many relays are needed and the load current requirements are low.
Note: Optocouplers and solid state relays are designed for use in signal processing networks, which are not supplied by the low-voltage power supply networks.
The basic principle used for optimum cycle control is zero cross control, which determines the ON/OFF status each half cycle. A waveform that accurately matches the average output time is output.The accuracy of the zero cross function is the same as for conventionally zero cross control. ...

In this article, we will briefly discuss the SSR (Solid State Relay), its construction, operation, Schematics & different types of SSR relays based on its switching property and input/output forms. We will also discuss the advantages & disadvantages of Solid State Relay (SSR) comparing to Electromagnetic Relays (EMR) relay.

Here’s the Solid State Relay (SSR) blog I promised in my last one on mechanical relays. SSRs perform the same basic functions as mechanical relays, but here I will cover how they function internally, why you would choose them over a mechanical relay, and go over some terminology. SSRs are made up ...
Solid-state contactor. A solid-state contactor is a heavy-duty solid state relay, including the necessary heat sink, used where frequent on-off cycles are required, such as with electric heaters, small electric motors, and lighting loads. There are no moving parts to wear out …

Unlike electro-mechanical relays (EMR) which use coils, magnetic fields, springs and mechanical contacts to operate and switch a supply, the solid state relay, or SSR, has no moving parts but instead uses the electrical and optical properties of solid state semiconductors to perform its input to output isolation and switching functions.
