What is the maximum operational temperature range for this relay?


The relay operates efficiently across a temperature range from -20°C to +70°C, ensuring reliable performance under varying conditions.

How does the zero cross feature benefit electrical control?


Employing zero cross switching reduces electromagnetic interference by ensuring that the relay turns on when the voltage crosses zero, minimising inrush currents and potential damage to sensitive components.

What kind of applications benefit from the use of an SPST relay?


An SPST relay is beneficial for straightforward on/off control applications, making it ideal for scenarios requiring simple switching mechanisms in industrial and commercial setups.

What is the significance of the maximum turn-on time?


The maximum turn-on time of 20ms allows for rapid switching of loads, enhancing the responsiveness of the control system and improving overall efficiency in automation processes.

Can you explain the role of off-state leakage current in this relay?


The off-state leakage current of 3.5mA is crucial for indicating power loss when the relay is not engaged, which helps in assessing the energy efficiency and performance of circuit systems.
