TCS310 Output Voltage

Hi,

In my last question I asked what the TCS310 Color Sense gives as output. The answer was that every output (R,G and B) would give 1 – 5V output signal. I want to connect this sensor directly to my PLC without having to use an Arduino board. I use a power supply of 5V DC with a 500mA max current. I measured the output directly on the pins between R/G/B and the ground. The sensor does react on different colors but has never given a output greater then 120mV. If tried multiple sensors as we orders 4 pieces, tried to switch between high and low sensitivity by using the jumper and with and without back light. Could you please advise?

 

Kind regards,

It is more than possible that the PLC is syncing too much power from the chip, but to be sure could you put an answer up with a picture of your setup? I also added the datasheet for the chip to the product page https://www.virtuabotix.com/productpage/609224532146/#tabs3-tab. Let me know whatever I can do to help, I would love to work with you to get direct PLC connectivity, and write an article with our findings to help others with the same issue.
