Universal usage. 2 separate monostable relays with each 2 double-pole double-throw. The relays have no limit switch, nevertheless they can be driven with steady current. The control takes place by negative switch impulses resp. steady current, AC voltage or digital current. Due to internal electronics the relay is noiseless even by connection to digital circuits or pulsed signals. It is suitable to connect light signals to modules which otherwise only control colour light signals, e.g. item-No.
