Alternation relay for the control of 2 electric pumps or compressors, in an alternative way. Operating voltage 230/400Vac and output by 2 contacts of free potential for contactor control or starting circuit of electric pumps or compressors. Narrow profile, only occupies one module (18.5mm).

Operation: When the alternation relay receives voltage between terminals 2 and 10, one of the output contacts is closed, giving signal to the contactor of the pump or compressor, or the starter of the same for the start-up of the pump or compressor. When the signal between terminals 2 and 10 disappears, the output contact opens, stopping the operation of the pump or compressor. When voltage is received again between terminals 2 and 10, the other of the contacts is closed, giving signal to the contactor of the second pump or compressor, or the starter of the same for commissioning. The commissioning of the pumps or compressors occurs alternately, one or the other, at each voltage of terminals 2 and 10 of the alternation relay.
