PURPOSE:To facilitate various control operations of a power load by providing terminals capable of mounting additional circuits and package. CONSTITUTION:A load controller for a power Y-delta starter circuit has a load selection ON/OFF control circuit containing a photocoupler 20 and a diode bridge 30, a control operation system deciding circuit containing a control operation system selection package mount 40, a power load remote control circuit containing remote control relays AX1, AX2 and AX3, and an operation state display circuit containing various light emitting diodes G, R and Y. Then, terminals T10-T21 which can connect a switch circuit for switching between a remote operation control mode and a test operation control mode are provided. Further, an additional circuit which controls necessary power load is connected to the mount. |
