What is a control relay and what does it do?
A Control Relay is also known as a Relay, is a switch, an electromagnetic switch. A control relay allows electrical current to flow through a conducting coil that opens or closes a switch. It also protects the circuit current. With a control relay, users do not need to manually turn the switch to isolate or change the state of an electric circuit.
What can a Hella relay be used for?
As switch amplifiers used to control electrical loads in plug-in standard models, these electronic components can be controlled by control units. HELLA relays feature diodes or resistors to suppress interrupting voltage peaks in the relay coils and thus prevent interference voltage.
What can you do with an electromechanical relay?
Electromechanical relays, most often used as memory logic elements, make electric relay control possible. Learners will study applications of these vital components, as well as the available styles of control relays and their ladder diagram symbols.
How does a PLC work in a relay circuit?
A key concept to master, however, is the association of real-life conditions to switch status based on the “normal” representation of those switch contacts, whether the switches be real (relay) or virtual (PLC). Once this vital concept is mastered, both hard-wired relay control circuits and PLC programs become possible to understand.

How are diodes used in a Hella relay?
HELLA relays feature diodes or resistors to suppress interrupting voltage peaks in the relay coils and thus prevent interference voltage. To ensure a maximum relay lifetime, the contact material is selected in line with the most demanding quality requirements. Remote-controlled switch powered by electric current to switch high loads
What does a relay circuit diagram look like?
In a “ladder” diagram, the two poles of the power source are drawn as vertical rails of a ladder, with horizontal “rungs” showing the switch contacts, relay contacts, relay coils, and final control elements (lamps, solenoid coils, motors) drawn in between the power rails.
