Does a relay connected to a collector switch require an additional power supply?

Thread Content

For the collector switch signal of a level switch that is connected to a relay, should the collector signal of the level switch be connected directly to the input terminal of the relay, or is it necessary to insert a power supply between them? Is this power supply the voltage required by the relay?

Is it necessary to add another power supply between the relay and the collector switch in the diagram?
