Definitions

  • the invention relates to a contactor arrangement that can be constructed in a modular manner, which can be used in particular for use in a safety-related application, for example in an industrial automation system.
  • two contactors with NO contacts and NC contacts which are used to report the switching status, are connected in series.
  • the contactors are controlled by a safety switching device, which controls the contactors via output signals and can thus switch a load via the contactors.
  • a disadvantage of the known contactors is that the contactors, which are designed as separate switching elements, have to be wired to one another and to the safety switching device by the user himself.
  • the lateral attachment of the contactors to a safety switching device also requires a relatively large amount of space, since the total width results from the sum of the individual widths of the contactors and the safety switching device.
  • a device for the safety-related disconnection of a segment circuit in a fieldbus is known.
  • two contactors are provided for safety-related double switching of supply lines of a machine or a motor, which are coupled to one another via a connecting line.
  • the two contactors are connected in series with normally open and normally closed contacts and are controlled by a safety terminal via output signals.
  • the contactors designed as separate switching elements are wired to each other and to the safety terminal.
  • a busbar adapter for mounting electrical installation devices, with internal contact rails for Current collection from the busbars is equipped.
  • the busbar adapter has on its upper side, ie on the side facing the installation devices, sockets which are accessible from above and which are connected to the contact rails.
  • a plug-in module that can be plugged into these sockets on the adapter has corresponding foot contacts on its underside for this purpose and is used for the electrical connection of the sockets of the contact rail to the mounted installation device.
  • plug-in contacts or output contacts for plugging into the sockets of an installation device are attached to the front of the plug-in module, which are electrically conductively connected to the foot contacts of the plug-in module.
  • a rigid contact bridge can be arranged, which has protruding plug contacts attached on both sides.
  • the switchgear assembly consists of a base and a set of power conductors intended for feeding the loads, for each load a pair of devices mounted on the base and a circuit breaker and a contactor, the pairs of devices being juxtaposed on the base.
  • the base has a support surface for accommodating multiple device pairs, power pins, and control pins that interface with the respective power and control terminals of the device pairs.
  • One of the devices of each pair of devices sits on the power pins and the control pins of the socket according to a mating direction that is substantially parallel to the support surface.
  • the safety switching device is usually housed in a housing with a standard width of 22.5 mm, while the two contactors are each housed in a standard housing with a width of 45 mm. This results in a total width of 112.5 mm for a safety switching system.
  • the invention is based on the object of creating a modular contactor arrangement which requires little installation space and can be set up without additional electrical wiring having to be carried out.
  • a core idea of the invention can be seen in the fact that two contactor modules are arranged one behind the other by means of a coupling module, the contactor modules and the coupling module only having to be assembled by a user without external wiring in order to be mechanically and electrically coupled to one another.
  • the overall width of the contactor arrangement is essentially determined by the narrow sides of the contactor modules in the assembled state.

  • the first electrical connections are arranged on the first connection surface and the second electrical connections are arranged on the second connection surface.
  • first and second predetermined width is between 20 mm and 30 mm.
  • a width of essentially 22.5 mm has proven particularly advantageous.
  • the side surfaces of the housing form longitudinal sides and the first and second connection surfaces of the housing form narrow sides.
  • the first electrical connections and the second electrical connections of the first can in the assembled state
  • Contactor module, the second contactor module and the coupling module lie in a common plane which is parallel or perpendicular to the base of the housing of the contactor modules.
