A mounting/dismounting unit is provided with a terminal block including connection terminals to be coupled with the connection terminals of the fixed unit. The mounting/dismounting unit has a hinge disposed at an end thereof and the fixed unit has a pin and a grip capable of being engaged with the hinge. The grip is pulled out to a position to be used and then further pulled out, whereby the mounting/dismounting unit is forced out, drawing an arc about the pin and separated from the fixed unit. With this arrangement, an I/O module with a mounting/dismounting unit capable of being easily removed is provided.Field of SearchMovable about axisIntegral retainer and cam separator Nonconducting pusher Including handle for direct manual urge to separate Pivotal movement Including compound movement of coupling part Insulating body having plural mutually insulated terminals or contacts (e.g., terminal block) Modular or multipart insulating body Coupling part Including bale or loop | |
