RELAY USING EXTERNAL MEMORY

摘要

PURPOSE: A device for easily processing set information of a relay is provided to update and obtain the set information of a relay by using an external memory. CONSTITUTION: A set information processing unit(750) stores relay set information of the storing mode in an internal memory(730) of the relay. The set information processing unit stores the relay set information of an extraction mode in an external memory(710). An external memory sensor senses the attachment and detachment of the external memory. If the external memory sensor senses the attachment of the external memory and activates the mode input unit. A mode input unit(770) selects the storing or extracting mode. The external memory is a USB(Universal Series Bus) memory.
