2 separate monostable relays with each 2 double-pole double-throw. The relays have no limit switch, nevertheless they can be driven with steady continous current. The control takes place by negative switch impulses resp. steady continous current, AC voltage or digital current. Due to internal electronics the relay is noiseless even by connection to digital circuits or pulsed signals. The relay is particularly suitable for the semaphore home signal item-No. 4702 for train control and for item-No. 5280 for frog polarization. Power input approx. 2 x 14 mA by 16 V. Power consumption: max. 2 A each changeover contact. |
