Current Output (DSA631-P07
4
~
20mA output unit)
Current output can be incorporated into the amplifier unit as an optional function. The current
output is made in a manner that allows the voltage output to OUTPUT2 to be converted into the
current output. When the output voltage of this product is changed from 0 V to +10 V, the output
current ranging from 4 mA to 20 mA can be provided. The central conductor of the BNC connector
delivers an output current, while its outer conductor serves as an output common. Turn the
OUTPUT2 level ADJ volume, which is located on the front panel, fully clockwise. When the
polarity of the output voltage varies from positive to negative, the output current starts decreasing
from 4 mA to approximately 0 mA. This 4 mA to 20 mA output unit can be built into the body of
this product if requested upon the delivery order (with extra cost). To add this current output
option to the already purchased product, contact out sales office or sales agent since your product
needs to be modified at our side. (Separately charged).

Table 6-1. Type of Case
We provide cases listed in Table 6-1. Select the case based on the number of channel to be used.
6-2-1. Accommodating Amplifier Unit
When accommodating amplifier units into a case, first the slit on the bottom of the unit should be
adjusted to the guide of the case. Press the amplifier unit slowly so that the power supply and
interface connectors are connected securely.
After installing all amplifier units, fix them with two screws at the top and bottom of the front face
an amplifier unit.
6-2-2. How to Mount Blank Panel
Blank panels are used to cover the area of a case where amplifier units are not installed. To fix
thepanel to the case, use top and bottom screws.
