  • Relay device having holding current stabilizing and limiting circuit
    Patent number: 7262950
    Abstract: A relay device includes plural relay units, each having a coil for opening/closing a contact point, a base plate made of resin and having wiring metal pieces, and a control circuit mounted on the base plate for controlling current supply to the coil. The control circuit has a function of stabilizing the holding current irrespective of environmental variation. Thus, the holding current can be further reduced and heating and power consumption can be reduced without losing the function of keeping the contact point state.
