Document Type and Number:

Japanese Patent JP7439468

Kind Code:

B2

Abstract:

The invention provides a programmable controller module and a programmable controller system. In a PLC module. Heat dissipation performance, vibration resistance and impact resistance are ensured without increasing the size. A PLC module (3) is provided with: a printed circuit board (6) on one surface of which a heat-generating component (C) is disposed; and a case part (30) that accommodates and supports the printed circuit board. The case part is provided with: a metal plate (31) provided so as to cover one surface of the printed circuit board; and a resin case (32) provided so as to cover a portion of the printed circuit board other than the one surface of the printed circuit board. The metal plate is in contact with the heat-generating component via the heat-dissipating fins (S), and heat-dissipating fins (33) are formed on the surface of the metal plate on the opposite side from the heat-generating component. The printed circuit board and the resin case are fixed to the metal plate.
