PURPOSE:To achieve small-sized and low-cost devices and to improve the performance of general-purpose application, by the adoption of a unit module for a part converting a signal from sensors into an electric signal and for a part outputting a control signal through the reception of the electric signal, respectively. CONSTITUTION:The 1st unit A converts the level of a signal from sensors into an electric signal and the signal is outputted from terminals 2a and 2b. Temperature sensors and the like are built in and vent holes 3 are provided. Further, a fixing piece 4 is provided for installation. The 2nd unit B controls power application to electric equipment. Connection is made to the 1st unit A, a power supply and electric equipment with terminals 19a-19d and terminals 20a-20d. An illumination type switch is provided at the inside of the unit B, allowing to switch the control to manual control through the operation externally. |
