Input method (MC-3010A only)
Select the method of the analog data input, power voltage or power current.
Note 1: The input must not exceed the range of the input voltage, to prevent malfunc-
tion.
• Setting for voltage input: -10V to +10V or 0 to 10V (depending on the setting)
• Setting for contact input: Voltage 4mA to 20mA.
Note 2: When changing the input method, turn off the MC-3010A and on again to put
change in effect.
 Power voltage: Input the amount of power voltage change to the operational ampli-
fier.

 Power current: Pass the power current to the shunt resistor, 1kΩ/parallel (com-
bined resistance: 500Ω) to input the amount of voltage change at the both ends of
the resistor to the operational amplifier.
