摘要： An I/O module for an industrial controller provides single terminal outputs that may either sink or source current. This capability is provided through the use of dedicated sourcing and sinking transistors connected to the terminal and controlled by lockout logic ensuring activation of only the appropriate transistor in the correct phasing for sinking or sourcing operation modes.

摘要： A method of manufacturing a current switch magnetic intensifier that is constructed to be secured in generally close proximity to the stationary contact of the current switch. During termination of the communication of power through the contactor assembly, the magnetic intensifier accentuates a magnetic field associated with a stationary contact and increases the magnitude of a magnetic force directed to the arc arrestor. The intensifier is fitted proximate the stationary contact so that a pair of arc rails extend beyond the stationary contact such that a force of a magnetic field generated by the contactor magnetic intensified is directed in a common direction with a direction of reduced resistance of the pair of arc rails to ensure efficient, repeatable, and expedient transfer of a circuit termination arc to the arc arrestor.

摘要： A safety switch configured to determine whether a magnetically operated switch which forms part of the safety switch has been welded closed. The safety switch is configured to establish a first magnetic field in the vicinity of the magnetically operated switch. The magnetic field is arranged to move the magnetically operated switch from a first configuration to a second configuration. The safety switch monitors the state of the magnetically operated switch to determine if the magnetically operated switch has been moved by the first magnetic field, thereby determining if the magnetically operated switch has been welded closed.

摘要： A method of forming a switch assembly that includes a magnetic intensifier constructed to extend in generally close proximity to one of the stationary contact and the arc contact. During communication of power through the contactor assembly, the magnetic intensifier manipulates a magnetic field associated with current passing through the switch assembly and increases the magnitude of a magnetic force directed to the arc arrestor. Preferably, the magnetic intensifier is formed integrally with a turnback associated with one of the stationary contact or the arc contact. Such a construction simplifies the manufacture and assembly of the contactor assembly and provides efficient and repeatable arc suppression.
