RELAY DEVICE
First Claim
1. A relay device comprising:
- a plurality of mechanical relays each of which includes;
a coil;
a moving contact, a position of which changes in accordance with whether or not the coil is energized;
a load terminal conductive to the moving contact; and
a coil terminal connected to the coil;
a first bus bar including a loading circuit, wherein;
an electric current flows to an external load through the loading circuit; and
the loading circuit is opened and closed as a result of the change of the position of the moving contact;
a second bus bar including a coil circuit through which the coil is energized; and
a relay drive circuit packaged on the second bus bar and configured to open and close the coil circuit based on an operation signal, wherein;
the first bus bar and the second bus bar are stacked at predetermined intervals;
the plurality of mechanical relays is located between the first bus bar and the second bus bar;
the load terminal is connected to the first bus bar; and
the coil terminal is connected to the second bus bar.

Abstract
A relay device includes mechanical relays, a first bus bar, a second bus bar, and a relay drive circuit. The relay includes a coil, a moving contact whose position changes according to whether the coil is energized, a load terminal conductive to the contact and connected to the first bar, and a coil terminal connected to the coil and second bar. The first bar includes a loading circuit. A current flows to an external load through the loading circuit opened/closed when the position of the contact changes. The second bar includes a coil circuit through which the coil is energized. The drive circuit is packaged on the second bar and opens/closes the coil circuit based on an operation signal. The first and second bars are stacked at predetermined intervals. The relays are between the first and second bars.
