Viessmann 5552 Electronic Relay
Two independent latching relays, each with two toggle switches. The relays convert short input current impulses delivered by digital accessory decoders, push button panels, switching tracks or track contacts, into continuous current. The relays haven’t got real limit switch contacts but nevertheless they can be controlled by continuous current. They have a current consumption of 15 mA. Max. contact load 2 A. Switchable by positive DC (+) or AC.
