Input Type (Mc-3010A) - Furuno VR-7000 Installation Manual

Input type (MC-3010A)

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

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