Additional Details:

This relay typically features a single-pole, double-throw (SPDT) contact configuration. It can switch loads up to several amperes, depending on the manufacturer’s specifications. It is designed for through-hole mounting on printed circuit boards (PCBs). The operating temperature range is usually between -40°C and +85°C. The coil resistance is indicated as '225M', which means the resistance is likely 225 ohms. The relay offers electrical isolation between the control circuit (coil) and the load circuit (contacts), preventing interference and ensuring safety. Consult the manufacturer's datasheet for precise specifications, including contact rating, coil resistance, and operating characteristics.
