Output Port
Refer to the diagram above, the left terminal (Io) is for the
positive terminal for current output while the right terminal (Vo)
is for the positive terminal for voltage output. The middle
terminal (-) is the common ground for both current and voltage
outputs.
Only the voltage terminals output can give complimentary
voltage output (±10V)
4.3
Excitation voltage
Through the slide switch EXC, the A2A-D2 can provide either
12VDC or 5VDC excitation voltage to the load cell.
4.4
Gain
The A2A-D2 amplifier can be applied to any load cells with its
specified sensitivity. It can support 4 ranges of Gain. User can
select suitable gain that matches to the load cell’s sensitivity,
excitation voltage and output signal by configuring the excitation
slide switch (EXC), the 4-bit DIP switch, and the SPAN
potentiometer. Refer to Tables below for the DIP switch and Gain
range selection.
