Abstract

A foreign matter is prevented from intruding into a function unit from a portion where an external control line is disposed, and a foreign matter intrusion preventing process is eliminated, which is necessary in the portion where the external control line is disposed. The function unit comprises: an electronic relay (5) for controlling a load; a wire terminal block (2) to which connection wires are connected that are connected to the respective input and output connection points of the electronic relay (5); and a wire connecting means (3) provided at one end of a relay wire (8) connected to the wire terminal block (2) and used for connecting an external control line (10). The wire terminal block (2) is disposed on the front side of the function unit and the wire connecting means (3) is disposed on a chassis (15).

Description

technical field [0001] The present invention relates to a functional unit and a control center for controlling the operation of a load such as a motor, monitoring the operation status, and issuing an alarm. Background technique [0002] For the existing functional unit, a control line connection terminal block is arranged on the front inside the functional unit, and each input and output connection point of the electronic relay is connected to the control line connection terminal block. In general, a functional unit has multiple functions. Such multifunctionality is realized by adding devices to the electronic relay or changing the ladder sequence in the electronic relay. In order to use the desired function of the functional unit, an external control line is introduced into the interior of the functional unit and connected to a corresponding part of the terminals of the control line connection terminal block.
