Note
● [Note 1] If the ambient temperature exceeds 23℃, the output current must be
derated by 1.8 mA for every additional 1℃. The maximum output current is 170
mA at 40℃. When OP and 24V are shorted, the maximum output current is
calculated by the following formula: 170 mA minus current over the DI.
● [Note 2] Based on the maximum output voltage of the signal source, select 500 Ω
or 250 Ω impedance. For example, if 500 Ω is selected, the maximum output
voltage cannot be lower than 10 V so that AI2 can measure 20 mA current.
