Digital Output Connections
Low voltage digital outputs 1-4 signal connections are made to the
terminals labeled OUTPUTS 1, 2, 3, 4, and G on Figure 4. The terminal
labeled G is the common for all four digital outputs.
For input devices with a + and
– terminal for every input channel, output
terminal G will be connected to all negative digital input terminals.

Cascade Mode Multiple Unit I/O Connections
When using Cascade Mode (see page 19), I/O terminals I and O shown
in Figure 5 may be used to link together multiple converters, and
provide additional inputs and outputs for monitoring. An unlimited
number of units may be connected in this way.
To connect multiple units in Cascade Mode, connect terminal O on the
first converter to the I terminal of the second. Continue to connect
converters in this way until the last converter’s O terminal is connected
to the first converters I terminal.
