Solid State Relays

Solid state relays (SSRs) are switches controlled by an electric voltage or current, instead of the electromechanical relay’s traditional mechanical armature which is actuated by the power source’s magnetic field. Electric power components based upon solid state electronics can provide switches with several advantages over more traditional contact-switched circuits. These advantages include:

• SSRs Provide Longer Life Cycles & Superior Performance - Typically, solid state relays deliver more switching cycles before they fail than electromechanical relays. This increases their overall reliability and decreases downtime. In addition, SSRs are better suited for sensitive voltage and current applications.
• SSRs Require Less Power to Operate - Since they have no moving parts, SSRs don’t require the same amount of power to operate as electromechanical relays. This reduces overall power requirements and improves system efficiency.
• SSRs Have Lower Contact Resistance - Because their contacts are made from semiconductor materials, solid state relays reduce contact resistance and increase the accuracy of temperature and voltage measurements.

One of the most popular solid state relays is the MP240D4. This unit is ideal for applications requiring fast switching, high current, low noise, and durability. The MP240D4 comes with an 8-pin direct-connect terminal and internal protection circuits. It also has a direct logic drive design that allows for easy logic-level control, making the MP240D4 well-suited for use in high frequency switching systems such as brushless motors for robotics.
