. OPTIONAL FUNCTION
6.1 Current Output(56-201 4 – 20 mA 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 to +10 V, the output
current ranging from 4 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
OUTPUT 2 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 – 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 our sales representative since your product needs to be
modified. (Separately charged)
