DE2608683A1 - Electronic timer relay with digital display - has decade switch for digitally setting delay time and scale line comprising series of LEDs - Google Patents

Abstract

The electronic timer relay has a decade switch (3), for setting the delay time and an opto-electronic digital display (4) adjacent the decade switch (3), together with a scale line (6) comprising a row of LED's (5). These are operated in synchronism with the timer operation, one after the other, to provide an analogue display of the remaining duration of the delay time, comprising the difference between the time set via the decade switch (3) and that indicated by the electro-optical display (4). The scale line (6) may comprise a series of LED's (5) arranged in an arc around the electro-optical display (4) and the decade switch (3), which are positioned one above the other.

Description

Electronic time relay.

The invention relates to an electronic timing relay with digital Setting option for the delay time9 whose timing is digital and at the same time is displayed analogously 0 With the known timing relays, especially those with Synchronous motor and reduction gear, shows by the action of an electromagnetic Coupling an expiration pointer to the state of the expiration time on a time scale. These analog expiry time between the excitation and the standstill of a timing relay is to be measured has proven itself over the course of several decades and in the industry enforced0 Time relays are also known in which the delay times by means of a subtracting timer and have a digital display. This display can be mechanical (DT-OS 2005572) as well as electro-optical come into effect. The latter versions show through increasingly cheaper integrated Circuits have a rapidly increasing tendency. The ones with such a digital progress indicator equipped electronic time relays also have the advantage of a greater resolution and a more precise readability.

Except for the mentioned timing displays for electronic timing relays there are those that are equipped with an analog time lapse display. she comes Specially used in electronic tang time relays, including a moving-coil measuring mechanism is used.

For the user of electronic timing relays with the ones described above Possibilities of a sequence display for electronic time relays arises with the Planning of controls always dictates which version is preferred give is.

In order to anticipate these considerations, the invention is the idea based on creating an electronic, digitally adjustable time relay, which displays the time-out delay digitally and analogously.

The digital time lapse display is in the form of a deco counter in optoelectronic design intended for one or more decades. the analog display of the time lapse is in the form of a scale bar or scale ring, in which a large number of light-emitting diodes are used, held. Instead of a scale bar or a scale ring, in addition to the digital Display a measuring mechanism for analog display of a digitally working electronic Time relay step as a further embodiment.

As is well known, the advantage of the digital flow indicator lies in the more precise readability of the time values and the greater resolution of the delay time range.

The resolving power was 1: 10000 with an arrangement of decades of the maximum time range I) the advantage of the analog sequence display is that that the portion of a delay time that has already passed can be detected more quickly can, and what proportion up to the switching point of the delayed switching element is available. This is especially important when used by a person who has to operate a system, with the timing of several timing relays at the same time be observed rivers.

The exemplary embodiments of the rfind-mg explained in more detail.

Fig. 1 shows a timing relay in front view with a square frame, with four-part decade switch and with digital display as well as a scale bar for the analog display Fig, 2 shows a Zei trelais as in Fig. 1, but with one Ringskaia for an analog display.

FIG. 3 shows a timing relay as in FIG. 1, but with an analog one Display by means of a measuring mechanism.

The timing relay (1) shown in Fig. 1 with its square .-2rontrahmXen (2) has a digital setting option for the delay time using the four-part decade switch (3). The delay time is set with the time value is shown by a four-way 7-segment LED display element (4) 0 The elapsing delay time is displayed after the timing relay has been activated subtracting from the set time to be determined using the decade switch (3) be. Simultaneously with the digital display by means of the 7-segment indicator elements (4) the bar display, which consists of a large number of light-emitting diodes (5), acts (6) in full length, with the individual according to the elapsed delay time LEDs (5) on the scale bar (6) go out in the direction of the arrow (7), or the light-emitting diodes (5) light up one after the other in the ratio of the digital set time.

The arrangement of the timing relay (1) shown in FIG. 2 is under construction the digital and analog display is the same as the timing relay nagh Figo1. only occurs instead of the scale bar (6) the scale ring (8) o The difference between the one shown in Fig 3 illustrated timing relay (1) compared to those of FIGS. 1 and 2 is in the analog Display can be seen through an electrical measuring device (9). A digitally adjusted The delay time is indicated by the pointer (10) of the of the measuring device (9) initially displayed with full deflection, and it is during a deceleration process go back to the zero position.
