PROBLEM TO BE SOLVED: To provide a relay device capable of suppressing power consumption or a physical constitution further than the prior arts, and a relay system.SOLUTION: In a relay device 11, a plurality of electromagnetic coils (L1, L2 and LP) include a first electromagnetic coil L1 and a second electromagnetic coil L2 that are disposed in proximity. The relay device comprises: a first magnetic circuit formed by making a first magnetic flux flow to a first core 119 that pass a hollow part of the first electromagnetic coil L1 and a yoke Yk as the first electromagnetic coil L1 is electrified; a second magnetic circuit formed from a path that is different from the first magnetic circuit, by making a second magnetic flux flow to a second core 129 passing a hollow part of the second electromagnetic coil L2 and the yoke Yk as the second electromagnetic coil L2 is electrified; and a third magnetic circuit MC3 formed by making a third magnetic flux flow to the first core 119, the second core 129 and the yoke Yk as both the first electromagnetic coil L1 and the second electromagnetic coil L2 are electrified.SELECTED DRAWING: Figure 1 |
