24v DC Input for TM221CE16R from Sensor

Hi ALl,

I am using TM221CE16R for my plant automation. This controller of schneider only accepts 24v dc as input. Less than 5v is a definite low, and more than 15v is considered as a high state. The issue is that I am planing to use some sensors for water level detection, but I am sure non can provide output of 24v. What can be done? I can use the sensors as a switch to 24v supply to the PLC, but this is my last resort.

Any suggestions?

Thanks.

A lot of point level detection is simple switches, which switch an applied voltage.

What level detectors can't handle 24Vdc?

Are they reliable? Can you share the link of a few to buy them please?
