BCD to
Analogue
Converter |
Performing up to four
decade BCD to analogue conversion this unit is programmable for input range for
FSD and output signal range and type. The input range for full scale may be set
anywhere between 0 - 9999 and is programmed by four range switches. The output
signal span may be set to either 10mA, 20mA, 1V, 5V, or 10V and output zero set
to either raised or true zero. These combinations will generate the following
outputs: 0-10mA, 0-20mA, 2-10mA, 4-20mA, 0-1V, 0-5V, 0-10V, 0.2-1.0V, 1-5V and
2-10V. This unit also provides a trickle-charging output for battery-powered
optical encoders. |
