Figure 9: -PWM option
For the standard low power digital outputs found on the RIO-471xx the bandwidth is 50 Hz.
Part number ordering example:
RIO-47102-PWM
-HS
This option changes digital input 3 (DI3) to a high speed digital input. It is available on the RIO-47xxx as a
standard option. With this option, the input becomes a TTL level input that is differential with respect to
digital input 2 (DI2 is not available as an input with the –HS option). The maximum frequency of pulses that
can be captured is increased to 3Mhz. If higher values are required, please consult factory.
Figure 10: -HS Option
Part number ordering example:
RIO-47100-HS
-16Bit
The -16 option specifies 16 bit resolution on the analog inputs and outputs. This option is valid on the RIO-
4712x and RIO-472xx only.
