Micro 830 IF4 Analog Scaling

I'm using the AB Micro 830 with an IF4 analog input card. I'm sending an analog signal from a Keyence FT-50AWP IR amplifier, but cannot figure out the correct scaling.

The Keyence is supposed to output a 4-20mA signal, with a range of 0 - 500 celsius. When I see the value in the PLC, it is 15300 for 20C, and 16580 for 33C.

This is something like 100 units per degree, and I have no idea what the scale is actually supposed to be. Most analog cards are scaled to 32k? Maybe I'm missing something?

Thanks for any help.

You select the raw data format when you configure the card.

See page 8 of link below for the range values of different data formats.

See page 9 for how to convert the raw data to engineering units.

Or see txt for scaling formula.

Please Note: The above link is actually for the Micro850 which uses a different analog module then the Micro830

If your using the 2080-IF4 analog module make sure you have the input set for "Current" and you have your sensor hooked up to the CI for that channel.

Now the "Raw Read" will be between 0 - 65535 so a 4-20 ma sensor will start at 13107 this would be your input minimum for the scaler and the max would be 65535.

Your output should be 0 celsius for the low and 500 for the high.

Should put you real close to what you are looking for.

Thanks everyone, I think the second post cleared it up.

Where did you find the 0 - 65535 range? I was looking for something like this, but none of the manuals had it.

Page 72 of this manual gives the "DATA RANGE" for the 2080-IF4 analog module.
