Electronic device

An electronic device comprising:

• a base plate;
• a plurality of modules detachably fitted and connected to the base plate;
• a plurality of mounting members configured to detachably mount the base plate to a DIN rail;
• and
• an operation lever provided on the base plate and configured to be engaged with the mounting members and to be operable from a front surface of the base plate,
• wherein when the operation lever is operated, an engaged state between the mounting members and the DIN rail is released;
• wherein the base plate comprises a first recess portion which is formed in a longitudinal direction and in which the DIN rail is fitted, a second recess portion formed in the longitudinal direction in parallel with the first recess portion, and third recess portions, formed to be orthogonal to the first recess portion and the second recess portion, provided in a back surface of the base plate,
• wherein the plurality of modules are detachably fitted and connected to a front surface of the base plate,
• wherein the plurality of mounting members are configured to be slidably fitted in the third recess portions of the base plate,
• wherein the DIN rail is configured to be fitted in the first recess portion,
• wherein the operation lever is configured to be slidably fitted in the second recess portion of the base plate,
• wherein when the operation lever is operated by being pulled from the predetermined position of the second recess portion, the mounting members are slid on the third recess portions so as to move away from the DIN rail.
