Abstract
An I/O unit has a fixed unit such as a housing provided with a multiplicity of connection terminals and an LED display module unit. 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.
