Abstract: A device includes a device input, an output connector configured to connect to a current loop, and current loop transmitter circuitry. The current loop transmitter circuitry receives, via the device input, an input from a dry contact switch, and translates a state of the dry contact switch to a current loop current. The current loop transmitter circuitry transmits the current loop current via the output connector through the current loop.

Abstract: A system includes a relay system and a controller. The relay system includes a relay having a first contact on an input side of the relay, the input side coupled to a power source, and a second contact on a load side of the relay coupled to a load. The controller is configured to monitor a current flow from the power source through the relay, transmit a close signal to the relay, and to transmit an open signal to the relay. Based on the current flow through the relay following the open signal, determine whether an electrical weld of one of the first contact and the second contact of the relay exists.

Abstract: An electromechanical relay includes a relay housing enclosing a contact chamber of the relay and a contact arrangement arranged in the contact chamber. The contact arrangement has a movable armature and a coil for moving the armature, a shaft connected to the armature, and a contact bridge arranged on the shaft for contacting stationary relay contacts in the contact chamber. A monitoring switch with switch contacts for monitoring the switching state of the relay is arranged in the relay housing. The switch contacts can be actuated by an actuator displaced by the contact arrangement. The monitoring switch of the relay has a switch housing which is separate from the relay housing. Additional protection and improved sealing of the monitoring switch mechanism can be achieved as a result, which leads to a long-lasting and reliable function of the monitoring switch.

Abstract: Systems and methods are provided for releasing welded-shut contactors of a contactor system. An exemplary contactor system may include a contactor and a controller. The controller may be programmed to command a vibration across portions of the contactor as part of a weld release control strategy when the contactor is welded closed. The vibration may be achieved by repeatedly alternating between energizing and de-energizing a coil of the contactor in order to mechanically shock/vibrate a welded contact of the contactor.

Abstract: A controllable switch, a dual-control switch, and a control system including a controllable switch includes a wireless communication module and a switch component. The wireless communication module is coupled to the switch component. The wireless communication module is configured to send a control instruction to the switch component in response to receiving a switching request. The switch component is configured to switch from a first state to a second state after receiving the control instruction. The first state is one of a turning-on state and a turning-off state, and the second state is the other one of the turning-on state and the turning-off state.

Abstract: A relay is disclosed. In an embodiment a relay includes a first switching contact having a first main contact, a second main contact and a first movable contact; a second switching contact having a third main contact, a fourth main contact and a second movable contact, wherein the second switching contact is electrically isolated from the first switching contact; and an actuator configured to move both the first and second movable contacts from a first switching state into a second switching state by moving a drive element of the actuator from a first position into a second position.

Abstract: A microelectromechanical systems (MEMS) switch device including current sensing and overcurrent protection can include a movable plate movable between an open position and a closed position, wherein the moveable plate is moved by applying at least one or more of an electrostatic force and a magnetic force to move the movable plate. The movable plate can include a shunt operable to conduct current when the movable plate is the closed position. An inductive coil electronically coupled to the shunt can detect current conducted through the shunt.

Abstract: A contactor apparatus and method for operating the contactor apparatus can include a contactor assembly with a contactor coil operably coupled to a contactor switch. One or more sensors can be provided in the contactor assembly adapted to measure one or more aspects of the contactor assembly. Based upon the measured aspects, a controller can initiate operation of the contactor switch to effectively toggle the contactor switch at a zero-crossing point along an alternating current waveform.
