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.
