Abstract: An optical device includes a beam-forming element made of a first material with a base surface and a top surface, which are opposite one another, and with a surrounding lateral surface, which connects the base surface and the top surface to one another. The optical device includes a support body made of a second material, which is formed with a receptacle for the beam-forming element and has at least one common contact surface with the lateral surface. The first material and the second material are in direct contact with each other. The first material is permeable to, and the second material is absorbent to, a defined electromagnetic radiation. A defined refractive index (n2) of the second material is set in a defined ratio to a defined refractive index (n1) of the first material in order to set a specific transition characteristic for the defined electromagnetic radiation at the contact surface.

Abstract: An apparatus for monitoring inerting in an exhaust gas discharge of a production facility includes a first flow measuring unit; a second flow measuring unit, and a monitoring unit. The first flow measuring unit is connectable to a first flow meter arranged in a first supply line of a first gas to the production facility and the second flow measuring unit is connectable to a second flow meter arranged in a second supply line of a second gas to the exhaust gas discharge. The first flow measuring unit determines a first gas quantity supplied to the production facility and the second flow measuring unit determines a second gas quantity of the second gas supplied to the exhaust gas discharge. The monitoring unit triggers a safety-related control function based on the determined first and second gas quantity.

Abstract: A modular control apparatus comprises a central control module with a first logic unit and a second logic unit, first electronic modules connected to the first logic unit and having safety inputs and safety outputs, wherein the first electronic modules are designed to provide safety functions of a safety controller, and second electronic modules connected to the second logic unit and having inputs and outputs, wherein the second electronic modules are designed to provide standard functions of a programmable logic controller. The central control module and the first and second electronic modules are arranged in a row of modules. The safety functions of the first electronic modules are defined by positions of the first electronic modules in the row of modules and/or by fixed hardware settings, and the standard functions of the second electronic modules are programmable.

Abstract: An interface adapter for controlling a track-side object of a railway installation includes an analog input from an external source and an analog output to drive an electromechanical relay circuit. A bidirectional digital communication interface communicates digital data including first digital data transmitted and second digital data received. An analog-to-digital converter coupled to the analog input is configured to generate a first digital signal representing the electrical input. A digital-to-analog converter coupled to the analog output is configured to generate the electrical output in response to a second digital signal. A power supply supplies electrical power to the digital-to-analog converter. A programmable logic control circuit includes a control program configured to produce the first digital data from the first digital signal, transmit the first digital data using the digital communication interface, process the second digital data, and produce the second digital signal in response to the second digital data.

Abstract: A control device for controlling a technical installation includes a guard module. The control device has a modular structure with an input module, which receives an input signal representing a state of the technical installation, and an output module, which outputs an output signal controlling the technical installation based on the input signal. A guard module is integrated into the modular structure to monitor operability of the input module and the output module. The guard module confirms the output signal of the output module based on its monitoring of the input module and the output module. Within the modular structure, the input module and the output module form a first potential group. The guard module forms a second potential group within in the modular structure. The second potential group is independent of the first potential group.

Abstract: An access protection system for safeguarding an access point to a machine or installation includes a sensor device and an interlocking device. The sensor device includes an optical transmitter and receiver. The interlocking device includes a base body and a blocking element. The optical transmitter is configured to transmit a light pulse to the optical receiver. The sensor device is configured to generate a sensor signal based on reception of the light pulse. The sensor signal is used to control the machine or installation. The blocking element is movable relative to the base body from a release position into a blocking position. The blocking element is configured to be located, while in the blocking position, in a beam path of the light pulse between the optical transmitter and receiver to block the reception of the light pulse. The interlocking device is lockable in the blocking position by a securing element.

Abstract: A digital input circuit for receiving digital input signals of at least one signal generator comprises first and second subcircuits. Each subcircuit includes a digital input to receive a digital input signal and a threshold value element to determine a logic state of the subcircuit. Each subcircuit adopts a first state in response to its digital input signal reaching or falling below a lower threshold value and adopts a second state in response to its digital input signal reaching or exceeding an upper threshold value. The digital input circuit further comprises a combined test and current increasing apparatus to generate a driving signal such that a function test of both the first and second subcircuits is conducted simultaneously with the driving signal and an input current of the digital inputs is increased.
