Abstract

1. A signal display device, in particular for signal arrays using racks of digital signal or carrier frequency systems, comprising a series circuit of luminescence diodes (A', B'...N') for the display of signals and a current source connected to a signalling voltage (Us ), comprising relays (A, B...N) which can each be driven by a signal, comprising first relay contacts to each relay (A, B...N) which can effect a short-circuit of the respectively assigned luminescence diode (A', B'...N') or a connection thereof to the signalling voltage (Us ) and comprising second relay contacts (a2, b2...n2) to each relay (A, B...N) as indicator contacts to collective lines which lead to a light signalling device, an acoustic signalling device and/or a central operation observation unit, characterised in that the current source consists of a transistor (T) with an emitter-resistor (R2), the base of the transistor (T) is assigned, as reference voltage source, a Zener diode (Z) whose series resistor (R1) is connected to a supply input (S) and that the first relay contacts consist of change-over contacts (n1', b1'...n1') which, when the respective assigned luminescence diodes (A', B'...N') are released, establish a connection to the supply input (S) from that side of the luminescence diode (A', B'...N') remote from the transistor, directly in respect of the luminescence diode (N') furthest from the transistor (T), and via a decoupling diode (DA, DB) in respect of the other luminescence diodes (A', B').
