Quick question for you guys. I'm a little confused about something. I have a 1762-IF4 analog module and a pressure switch wire to it.

The pressure switch specifications calls for 0-40000 PSI range and a 4-20Ma output.

When I looked at the "Scale with Parameters" function with the sensor wired on input # 1 and zero pressure because the system is not running the number displayed at the SCP shows 6242.

I was reading the Allen Bradley manual for analog cards and I though I read that the integer representation for 4 - 20 ma was the following,

3277 - 16384 (Analog Input Signal)
6242 - 31208 (Analog Output Signal)

Am I understanding this correctly?

Jose
