摘要： A safety circuit arrangement for the fail-safe connection or disconnection of a hazardous installation (24) has a control device (12) which is designed to connect or interrupt, in failsafe fashion, a power supply path (20) to the installation (24). The safety circuit arrangement also has a signalling device (14) which is connected to the control device (12) via a number of lines (50, 52). The signalling device (14) has an actuator (40) which can change between a defined first state and a second state (40'). A pulse generator (42) in the signalling device (14) is designed to generate a defined pulsed signal (44) with a large number of signal pulses (46) on the lines (50, 52) when the actuator (40) is in the defined first state. According to one aspect of the invention, the signalling device (14) is connected to the control device (12) via a two-wire line (54) with a first and a second core (50, 52). A predominantly constant voltage is present between the two cores (50, 52) when the actuator (40) is in the second state. The pulse generator (42) is designed to bring about a voltage dip between the first core (50) and the second core (52) in order to generate the large number of signal pulses (46).

摘要： The invention relates to a device for reliably controlling the closing position of two parts that can move relative to one another, comprising an actuator (16) and a sensor (18). The device can be particularly used as a door contact switch in a protective door for securing an automated technical installation The sensor (18) has a receiver circuit (46, 48) on the input side, said circuit generating a defined receiver circuit signal (52) when a switching distance (44) between the sensor (18) and the actuator is fallen short of. Also provided is a detector circuit (50, 58) that sends a release signal (66) when the defined receiver circuit signal (52) is available. According to one embodiment of the invention, a test element, particularly in the form of a switch element (72), is provided, said element being configured to suppress the receiver circuit signal (52) in a targeted manner.

摘要： A safety switching device for fail-safe disconnecting of an electrical load (26a, 26b) has an input part (44) for receiving at least one safety relevant input signal, a logic part (50) for processing the at least one safety relevant input signal, and an output part (54) which comprises a relay coil (56) and a first relay contact (60.1), a second relay contact (62.1), a third relay contact (60.2) and a fourth relay contact (62.2). The first and the second relay contacts (60.1, 62.1) are arranged electrically in series with one another. The third and the fourth relay contacts (60.2, 62.2) are also arranged electrically in series with one another. The first and the third relay contacts (60.1, 60.2) are mechanically coupled to one another, in order to form a first group (60) of positively driven relay contacts. Likewise, the second and fourth relay contacts (62.1, 62.2) are mechanically coupled to one another, in order to form a second group (62) of positively driven relay contacts. The logic part (50) controls the first group (60) and the second group (62) redundantly, in order to selectively allow, or to interrupt in a fail-safe manner, a current flow to the electrical load (26a, 26b), depending on the at least one safety relevant input signal. The relay coil (56) is electromagnetically coupled to the first group (60) and to the second group (62) of positively driven relay contacts, such that the logic part (50) can control the relay contacts (60.1, 62.1, 60.2, 62.2) together via the one relay coil (56). Mechanically, the relay contacts (60.1, 60.2) of the first group can however move separately from the relay contacts (62.1, 62.2) of the second group.

摘要： Process and device for the error-protected evaluation of a position indicator (32), in particular a potentiometer. The position indicator comprises at least one first connection and a second connection (34, 36) between which a defined total impedance is applied. The position indicator (32) also has an adjustable tap (38) at which a first and second partial impedances (40, 42) can be measured. The device includes an evaluation unit (12, 14) connected to the position indicator (32) in order to determine a momentary position of the tap (38) by means of at least one of the partial impedances (40, 42). The device further comprises a reference impedance (45) for checking the position indicator (32). In one aspect of the invention, the evaluation unit (12, 14) is designed to determine a first and a second measurement values representative of the first and second partial impedances (40, 42), respectively.
