Note 16: Voltage specification applies at barrel plug power input. The power supply provided with the

board meets this specification at the rated total power supply current. If a different power supply is

used, small line resistances could cause significant voltage drop between the power supply and the

barrel plug input.

Note 17: This is the total current requirement for the WEB-TEMP which includes up to 20 mA for the

LEDs and 10 mA for the user voltage output.
