The present invention relates to a relay module for controlling a vinyl house and a controller for the vinyl house using the same, in which it is possible to easily enlarge or expand the control capacity or function of the controller in accordance with the increase or decrease of facilities of the vinyl house such as a ceiling switch, and the controller of the vinyl house serves as a dedicated controller for the vinyl house as well as a controller of a controller group for the other vinyl house. The controller of a vinyl house according to the present invention includes: a module body forming a skeleton of a relay module； a plurality of relays provided in the module body； a connection pin group portion in which connection pins for electrically connecting to an external electric/electronic device for each relay are gathered； a relay module for controlling a plurality of vinyl houses, in which the relay module includes a plurality of basic control switches provided for each relay to control the electrical connection state of a corresponding connection pin of the connection pin group portion for each relay； and a plurality of operation mode selection switches installed corresponding to each relay for selecting an independent operation or a group operation of the relays； and a control group forming circuit portion which electrically connects the connection pins of the connection pin group portion of the relay module for controlling mutually different vinyl houses such that at least two relay modules for controlling the vinyl house are grouped and operated or one or at least two relays of the at least two relay modules for controlling the vinyl house are grouped and operated.COPYRIGHT KIPO 2018본 발명은 천정용 개폐기 등 비닐하우스의 설비물 증설 내지 축소에 따라 그 콘트롤러의 제어 용량 내지 기능의 확대 및 확충이 용이하게 이루어질 수 있고, 비닐하우스의 콘트롤러가 해당 비닐하우스의 전용 콘트롤러 및 다른 비닐하우스와의 연계 및 보완 작동이 이루어지는 콘트롤러 그룹의 한 콘트롤로로써 전환 작동이 이루어질 수 있도록 하는 비닐하우스의 제어용 릴레이 모듈 및 이를 이용한 비닐하우스의 콘트롤러에 관한 것으로서, 본 발명에 따른 비닐하우스의 콘트롤러는 릴레이 모듈의 골격을 형성하는 모듈 본체와,
