Embodiment Construction

[0045] figure 1 A schematic diagram of a system 2 is shown in , which is a component of an industrial plant not shown in detail. The system 2 has an actuator 4 in the form of an electromechanical valve, by means of which the flow of fluid, such as gas or liquid, through the tube is regulated. The actuator 4 has a supply line 8 and a ground line 10 which are in electrical contact with a supply network 12 . In this example, the power supply network 12 is provided by means of a rectifier, not shown in detail. The ground line 10 is furthermore electrically led to the ground 14 . A constant potential is conducted via the supply line 8 and the ground line 10 , a voltage of 200 V prevailing between them.

[0046] In addition, the system 2 has a controller 16 in which process parameters for manipulating the actuator 4 are stored in order to appropriately control / regulate the fluid delivery. The controller 16 is a programmable controller, by means of which further components not sh...

Abstract

The invention relates to a system (2) having a control unit (16) and an actuator (4) and an assembly (18) for providing functional safety. The assembly (18) has a switching unit (24) introduced into the power supply line (8) of the actuator (4), which switching unit is operated by means of a control device (22) of the assembly (18), which control device is connected to the control unit (16) in a signaling manner. The invention also relates to a structural assembly (18) and a switching unit (24).

Description

technical field [0001] The invention relates to systems with controllers and actuators as well as structural components. The structural components are used to provide functional safety and include switching units and controls. Furthermore, the invention relates to structural components as well as switching units. Background technique [0002] Plants, such as industrial plants, usually have one or more actuators by means of which activities are carried out. In industrial plants, for example, workpieces are created and / or machined by means of actuators. In order to operate the actuator according to the desired function, a controller is provided, by means of which the power supply to the actuator is regulated. In the simplest case, there are switches actuated by means of a controller. Here, the actuator is switched on and off by means of a switch. For this purpose, a switch is introduced in the supply line of the actuator. Switches, controllers and actuators form the syst...
