Specifications
Number of channels : 2
Input format : Balanced difference input
Input coupling : DC
Input resistance : 1 M
Ω
Gage ratio : 2.0
Excitation voltage : 2 V DC, within 5 V ± 0.2%. Has remote sens-
ing.

*At temperatures of +23˚C±5˚C
Pin Signal
number name
1 +BV Excitation voltage
2 –IN Signal input
3 –BV Excitation voltage
4 +IN Signal input
5 GND
6 +S Remote sensing signal of
7 –S excitation voltage
Notes:
• CS to +BV, and –S to –BV at the sen-
sor when remote sensing is performed, or at the
input connector when not performed. Otherwise,
a correct excitation voltage cannot be obtained.
• Be sure to connect the shield of the sensor con-
nector and the cable shield.

Connect the cables from the sensors to the input con-
nectors before turning on the power of the GX-1.
Otherwise, the precision may be lowered.
