Chapter 4 I/O
Introduction
The standard RIO controller has 16 digital inputs, 16 digital outputs, 8 analog inputs and 8 analog outputs.
The interrogation command,
TZ
, allows the user to get a quick view of the I/O configuration and bit status.
Specifications
Access to I/O points is made through the 44pin and 26pin High Density D-Sub connectors on the top of the
unit. Pinouts for the Connectors for RIO-47xxx are listed in the Appendix.
Digital Outputs
High Power Digital Outputs
On the RIO-471xx digital outputs 0-7 are opto-isolated sourcing power outputs. On the RIO-472xx all 16 of
the digital outputs are configured this way by default. 12-24VDC with 500mA of current capability per
output. The internal circuit diagram is shown in Figure 4:
Figure 4: High Power Sourcing Outputs
OP0A should be connected to the positive side of a 12-24VDC external power supply.
OP0B should be connected to Ground on the external power supply
OP0A and OP0B are the Output Power for Bank 0. The device that needs to be turned on/off (solenoid,
relay, etc…) should be connected with the positive side of the device connected to the digital output DO [7:0]
and the negative side connected to the Ground of the power supply. When the SBn (Set Bit n) command is
