When switching high current on restricted space or a high short- circuit strength is required or when switching several power circuits with one control signal, you have to use relays.
potential- free outputs in controls
galvanic separation of load and control circuit
The power miniature relays have a high maximum continouos current of 8 A at a small size.
The bi-stable relays from Dold store the switching state mechanically, i.e. after switching no energy is necessary.
Dold miniature relays are available in different versions, eg: SMD version or DIL version (suitable for 16- pole IC- sockets)
Sockets for PCB assembly or for mounting on DIN rail available for Dold PCB relays.
To switch different voltage circuits or high load with a controller, potential free relay outputs are most suitable.
As coupling module:
Flexible interface module which can be used as a input or output module.
In installation modules:
Use of bistable Dold relays, eg: in stair case lightening relays
