Dual-channel Mode
When dual-channel mode is used, output channels function as connection
pairs. Connection pairs are as follows:
• Channels 0 and 1
• Channels 2 and 3
• Channels 4 and 5
• Channels 6 and 7
When both output channels in a connection pair are in the On state and
without any faults, the safety outputs are turned on.
For information on how to use dual-channel mode with a 5069-OBV8S or
5069-OBV8SK module affects the safety application suitability level, see
Table 44 on page 143.
Figure 20 - 5069-OBV8S or 5069-OBV8SK Dual-channel Mode (Not to Scale)
IMPORTANT Dual-channel mode is only available if the module is connected so that
Output Mode is Sourcing.
