T91-1C 6V 30A General Purpose Relay TTP223B Module There's also 128 KB of6V 30A is a general purpose relay. Mostly, relays are used to perform switching operations without manual touch. It is used to control the flow of current. General purpose Relays are primarily used as a control circuit (relay sequence) for automated machinery employed at various industrial sites as well as for other control systems including lighting, air conditioning, and water treatment in buildings. Applications When galvanic isolation is desired,
