Analog control Solid State Relay

Analog Control Solid State Relays (SSR) differ from traditional SSRs mainly in control methods and application scenarios. Traditional SSRs use switch-type control, operating through digital signals (e.g., 3-32Vdc or 90-280Vac) to achieve on/off states, making them suitable for simple switching tasks like motor starting or heater control. In contrast, Analog Control SSRs support analog signal inputs (e.g., 0-10V, 4-20mA, 10k potentiometer) to achieve linear adjustment of output based on the input signal, making them ideal for precise control scenarios such as temperature regulation or lighting adjustment. Compared to traditional SSRs, Analog Control SSRs are more complex, featuring high-precision control circuits to meet advanced industrial automation needs. Overall, Analog Control SSRs offer greater control precision and flexibility, while traditional SSRs are better suited for basic on/off control tasks.
