Part number ordering example:
RIO-47200-(1LSNK,2LSRC), where
1LSNK: Outputs 0-7 low power sinking
2LSRC: Outputs 8-15 low power sourcing
-QUAD, -SSI, and -BiSS
Most RIO models utilize Digital Inputs 12,13,14 and 15 and Digital Outputs 12,13,14 and 15 as
encoder inputs. These digital inputs and outputs will not be available as standard digital I/O when
the -QUAD, -SSI, or BiSS option is ordered.
RIO-472x2 and RIO-47300 models have additional board that does not require sacrificing I/O for
the benefit of encoder inputs, but modifies the physical dimensions of the unit, see Special Note
for RIO-47202 and Special Note for RIO-47300 below for more details.
The QE command is used to read the encoder register, the WE command sets the current
position of the encoder (-QUAD only) and the SE command configures the encoder when the –SSI
option is ordered. The register that is read using the QE command is updated by the RIO every
25ms. See the QE, WE and SE commands in the RIO command reference for more information.

Hardware update rate. Register read by the QE command is updated at a rate of 40Hz.
Special Note for RIO-47202
The RIO-47202 allows for QUAD, SSI, or BiSS encoder monitoring through an optional plug-in
screw terminal board similar to the SCB-48608 shown in Figure A.1 below. The Encoder
monitoring option has a 25msec update rate and is not available with the Analog output option.
An external power source is required to power the encoders.
