given, this will provide a positive voltage to the device on the output pin to turn it on (with up to 500mA of
current available). A CBn (Clear Bit n) will remove the voltage to turn it off. The
bold
connections in Figure
4 are external connections.
RIO-471xxx
There are two internal 2 Amp fuses for the high power outputs, one fuse for outputs 0-3 and another fuse for
outputs 4-7. These fuses are not field-replaceable.
RIO-472xx
OP1A and OP1B are the Output Power for Bank 1 – digital outputs 8-15.
There are two internal 4 Amp fuses for the high power outputs, one fuse for outputs 0-7 (OP0A/OP0B), and
another fuse for outputs 8-15 (OP1A/OP1B). These fuses are not field-replaceable.
Low Power Sinking Outputs
Digital Outputs 8-15 are opto-isolated sinking outputs on the RIO-471xx (by default none of the digital
outputs on the RIO-472xx are configured this way). If ordered with -08-15 SOURCE option, please see the
section below. 5-24VDC with 25mA of current capability in a sinking configuration.
Figure 5: Low Power Sinking Outputs
OP1B should be connected to the positive side of a 5-24VDC external power supply.
OP1A should be connected to Ground on the external power supply.
OP1A and OP1B are the Output Power for Bank 1. The output can sink up to 25mA of current. The device
should be connected between the digital output DO[15:8] and the positive side of the power supply. When
current is
not
flowing through the opto-coupler (CB), the 10k resistor pulls-up the output pin to the voltage
supplied to OP1B. When current
is
flowing through the opto-coupler (SB), the digital output drops to
Ground (supplied by OP1A) and is able to sink up to 25mA of current. The
bold
connections in Figure 5 are
external connections.
OUTC jumpers
The OUTC jumpers can be used when an external power supply is not desired for digital outputs 8-15. These
low power outputs can use the in5V from the RIO instead. To do this, place a jumper on the pins
labeled OUTC as shown here:
Note: These jumpers DO NOT supply power to high power digital outputs;, an external supply is required
for these outputs
