RIO Outputs

The RIO has four transistorised outputs. Each output is connected to +12 V via a 3k3Ω pull-up resistor
(refer to Table 3-4). When an output is activated, the load is switched to the negative supply voltage (ground
or 0 V) of the RIO. The current available from each output is 400 mA.
The default functions and pull-up resistors of each RIO output, when connected to a Galaxy are shown in the
following Table:
