Hello guys,
I wanna use an ultrassonic sensor outputs to alarm, but I'm not sure if it has enough current.
Description:
I have an ultrassonic sensor which features 2 individual NO PNP outputs. It's a diffuse sensor and I'm using it to alarm the distance to a wall. The sensor will be stuck on a moving object.
Having 2 individual outputs (A and B) means that I can program the sensor so A outputs 24V within a 3m range from the wall and B outputs 24V within 1m range from the wall.
So I wanna use output A to light a light emitter, and output B to sound an alarm.
Both sensor and alarms work with 24V CC.
The issue is:
Max. output current of the sensor is 100mA.
Light emitter needs 110mA. Sound alarm needs 120mA.
I can't run a test right now because I still haven't received them yet.
Here's the "schematic":
I'm guessing I'll need "something" between the outputs and alarms so I have enough current to power both at the same time when needed. Relay? 1 or 2? Auxiliary contactors? I don't much about them. Can you suggest a product?
I need a light. Please help.
Thank you!
