Output Ramps
The C500-DA501 is a Special I/O Unit for the C500, C1000H, C2000H, CVM1,
and CV-series PCs. It has eight analog output points and the following functions.
• Output signal range can be selected for each output point (0 to 10 V, 0 to 5 V, –5
to 5 V, –10 to 10 V, 0 to 20 mA, or 4 to 20 mA).
• Either BCD or binary format can be selected for the conversion data for each
output point.
• Scaling can be set for each output point.
• Upper/lower limits can be set for each output point.
• An output ramp can be set for each output point.
• High-speed conversion can be set for all eight output points (only when scal-
ing, upper/lower limits, and output ramps are not used).
Output Signal Range Selection
Output signal
range can be
set.
Scaling
Conversion data can be set in
engineering units. The scaling
upper and lower limits are set.

Conversion data
Note Reverse scaling (lower limit: 100%, upper limit: 0%) is also possible.
Output ramps can be used to make output signals change at a specified rate to
prevent sudden changes in response to changes in conversion data.

BCD/Binary Mode Selection
Either BCD or
binary can be
set.
Upper/Lower Limits
Output signals remain constant when
conversion data exceeds the upper limit
or drops below the lower limit.
