Continuum I/O System Reference
73
The AO-4-8, Continuum’s analog output module, has four analog outputs with eight-bit
resolution, which can be configured as either voltage (0-10VDC) or current (0-20mA)
outputs. The AO-4-8 is the perfect choice for valves, dampers, variable speed drives, and
similar equipment that demand high control accuracy.
An AO-4-8-O model with full override capabilities is also available. Each output contains
a three-position manual override switch and override potentiometer. In addition, the AO-
4-8-O provides software override feedback to Andover’s
Plain English
programming
language for each output.
