+10 to 0 (VDC)/0 to 100 (%) (Inverse operation)
* Input impedance: 22 kΩ
* The allowable maximum input is +15 VDC; however, the voltage higher than
+10 VDC is treated as +10 VDC.

+20 to 0 mA DC/0 to 100% (Inverse operation)
protection.
* Input impedance: 250Ω
* The allowable maximum input is +30 mA DC; however, the current larger
than +20 mA DC is treated as +20 mA DC.
