APPENDIX F – 190-DAC OPTION
The 190-DAC is an option card for the 190 that outputs an analog 0-10V or 0-24mA. The user
can control the output voltage or current using the DAC interface in the 190. The DAC has
sense jumpers that allow the user to connect the 190-DAC card voltage or current lines long
distances.
If the Voltage or Current lines need to go long distances the user will need to connect the
polarized sense lines as close to the other end connections as possible and remove sense
jumpers J1 (+SEN) and J2 (-SEN). Refer to the DAC Wiring section for the location of J1 and
J2. If the sense lines are not needed the jumpers need to be installed.
NOTE: The 190-DAC Option cannot be added in the field. It
requires
returning the
190 to the factory to perform the upgrade.
