To enable a safe monitoring with a small cabling effort of a modular safety relay circuit, a modular safety relay circuit for the safe control of at least one machine is provided comprising a safety relay unit that has at least one forcibly guided relay for the safe switching on and off of the machine and that generates output signals in dependence on input signals, wherein the input signals are provided by at least one connected signal transmitter and the output signals are communicated to the at least one machine; and at least one expansion relay unit for providing additional output connectors so that additional machines can be connected; wherein the expansion relay unit has at least one respective forcibly guided relay for the safe switching on and off of the machine and is monitored by means of a monitoring signal.

Modular safety relay circuit for the safe control of at least one machine

In order to enable a simple and secure handling on a wiring of a safety switching apparatus, a safety switching apparatus for the secure switching on and/or off of at least one electrical machine is made available that comprises at least one conductor plate having at least one control unit for controlling the electrical machine and having electrical contacts and a plug connector that can be plugged onto the conductor plate for electrically connecting to the contacts, wherein the plug connector is provided with first connector sockets for the connection of at least one signal encoder and with second connector sockets for the connection of the electrical machine.

Safety switching apparatus for the secure switching off and/or on of at least one electrical machine

The invention relates to a programmable logic controller having an energy supply that provides electric energy to operate the unit and having at least one measurement input, with the measurement input being configured to measure and/or detect an electrical input signal. The programmable logic controller is characterized in that at least some of the electric energy of the input signal is supplied to the energy supply.

Programmable logic controller

To enable an intuitive and inexpensive releasable fastening of a housing to a fastening rail, a fastening apparatus is provided for the releasable fastening of the housing to the fastening. A single-part lever mechanism is used for latching and unlatching the housing to and from the fastening rail. The lever mechanism has an actuation means that moves the lever mechanism into a latching position or into an unlatching position, a first lever arm that actuates a first hook provided in the housing in a first direction, and a second lever arm that actuates a second hook provided in the housing in a second direction. The first and second directions are opposite one another and the first and second lever arms are connected to one another via the actuation means such that a support section is formed that has a parabolic form having two parallel limbs.

Fastening apparatus for releasably fastening a housing to a fastening rail

To enable a fast configuration of a control or of a total plant, a control for the safe control of at least one machine is provided having at least one input unit for receiving input signals from at least one signal generator; having at least one output unit for outputting output signals to the at least one machine; having a control unit for generating the output signals in dependence on the input signals; and having a connection unit having at least one connection socket for connecting an external input device that can be used or configuring the control, wherein the connection unit has at least one connection terminal for connecting the signal generators and/or the machine and is separable from the control and wherein the connection socket can be removed from the connection unit or from the control and comprises a memory with configuration data of the control.

Control for the safe control of at least one machine

In order to reduce the power-loss in digital inputs of a safety control, a safety control for the secure operation of a technical plant is provided that comprises at least one input unit for the reception of a signal of at least one signal generator connected to the technical plant, a control unit for the reading in of the received signal and for generating a control command, and at least one output unit for the transmission of the generated control command to at least one connected actuator of the technical plant, wherein the input unit has a switching element at the input side that can be controlled by means of the control unit and is configured in such a way that the switching element can be actuated by means of the control unit directly prior to the reading in of the received signal, in particular can be closed, and can be actuated again by means of the control unit, in particular opened, following the reading in of the received signal.

Safety control for the secure operation of a technical plant and method of operating a safety control

To enable an addition or a removal of a control into or from a communication line without an interruption of the ongoing communication of the communication line, a method is provided of adding a control into a network of at least one first and one second control, which are provided for operating actuators, during an operation of the network, wherein the first and second controls are connected to one another in a communication line and communicate with one another via a first transmission connection of the first control and a second transmission connection of the second control; and wherein each control has an unambiguous identifier, comprising the steps of providing a third transmission connection and a fourth transmission connection between the control to be added and the first control to be connected upstream of the control to be added; providing a fifth transmission connection and a sixth transmission connection between the control to be added and the second control to be connected downstream of the control to be added; and activating the third to sixth transmission connections between the first and second controls and the control to be added on the simultaneous deactivation of the first and second transmission connections between the first and second controls and methods of removing a control from a network of at least one first and one second control and the control to be removed.

Methods of adding or removing a control into/out of a network and apparatus for carrying out said methods

The invention relates to a bus system comprising The bus system is divided into segments each having one or more consumers respectively associated with a current supply unit and which each have a first current supply line and a second current supply line. The first current supply line and the second current supply line are respectively not directly electrically conductively connected to the first current supply line and to the second current supply line of a different segment and are preferably separated from the first current supply line and the second current supply line of the other segment in a galvanic manner.
