电子时间继电器
Time Relays
Electronic time relays are specially adapted mechanical or solid state relays. They include a solid state or mechanical relay as well as an electronic timing circuit. This combination provides accurate timing control and isolation between the input and the load voltage, plus multiple switching contacts: 1 c/o (SPDT) or 2 c/o (SPDT). They are often used in OEM equipment, industrial and building applications, providing time-delayed switching for starting, control, regulation and protection. A large selection of timing functions, time delay ranges and adjustment options are available.
