General purpose relays HR series
|
General purpose relays are designed to control various types of loads inside machines, simple or very complex systems and plants.
They can command contactors, electrovalves, electric actuators, resistors, indicator lights, etc.
General purpose relays are controlled by PLC or by the electronic control devices of machines and plants.
These have contacts with reduced power; the relays have the purpose to increase power and multiply the command.
Another advantage of general purpose relays is PLCs and electronic control devices protection from damage due to possible short circuits on controlled loads.
In fact, an industrial relay damaged by short circuit can be replaced in a few seconds at a minimum cost compared to a long machine shutdown at high cost in the case of damage to the internal contacts of a PLC.
