Solid State Relays
A solid state relay (SSR) is a switching device that utilizes semiconductor technology to control and switch electrical circuits. It does this without any of the features associated with electromechanical relays, such as physical contacts, electromagnetic induction, or bulky coils. These relays are used in many applications, such as controlling the switching of electrical motors, light dimmers, and other electrical circuits. The LCA125STR is a new type of SSR module that combines an optically isolated input port with a solid state actuator.The LCA125STR SSR is a compact, single-channel, non-isolated, solid-state power control module. This module is designed to provide both control and power management capability in a single package. The module can be used for direct control of electric motors, light dimmers, and other electrical circuits. It is also suitable for use as a part of a mixed-control or hybrid system. It is available in three different power switching configurations: high-side, low-side, and dual-channel.The LCA125STR uses an optically isolated input to control the module. The optically isolated input is used to detect the presence or absence of an external input signal. If the input signal is present, the LCA125STR will activate its output relay. This allows for the precise control of powerful electrical loads without any of the common electrical noise issues associated with digital signals.The module utilizes a solid-state actuator to control an output relay. This solid-state actuator is capable of providing up to 150 mA current, enabling it to actuate the output relay. In its high-side configuration, the module can be used to control resistive loads up to 5 A, and inductive loads up to 2 A. It can also be used to switch AC loads up to 500 W. The module is protected against electrical overloading, with an in-built over-current protection feature.The LCA125STR also features a built-in power converter that can convert an input voltage of 5 to 42V DC into output voltage levels required by the external loads. This circuit can also be used to regulate electrical currents in applications where power conversion is required. The circuit features low input current leakage and low power dissipation.The LCA125STR is a highly efficient, compact, and reliable solid state relay module. Compared to traditional electromechanical relays, it has the advantage of being more compact, and it consumes less power. It also eliminates the risk of electrical noise, as it does not use any physical contacts or electromechanical induction. Finally, its over-current protection feature ensures that it is highly reliable and safe to use. The LCA125STR is an excellent choice for applications that require precise control over powerful electrical loads.
