TA1225 is A Solid State Relay (SSR) is an electronic switching device that is used to control electrical loads without the need for moving mechanical parts, as found in traditional electromechanical relays

A 25A Solid State Relay (SSR) is a type of electronic switch that is capable of handling currents up to 25 Amperes. Unlike traditional electromechanical relays, SSRs use semiconductor components like thyristors (SCRs) or triacs to perform the switching action. SSRs are typically controlled by low-voltage signals (such as 3-32VDC) and require very little current to activate the switch. They are compatible with various control signals, including digital logic signals and microcontroller outputs.

SSRs find applications in various industries, including industrial automation, process control, heating and cooling systems, lighting control, and wherever reliable and noise-free switching of high currents is required.
