Combination of double outputs
Both terminals of double outputs are turned on only when both safety remote outputs (SA\Y) are on. The safety remote I/O
module evaluates the logic of safety remote outputs (SA\Y) and determines the state of the output terminals. The following
table lists the correspondence between each state of safety remote output (SA\Y) and output terminal for double outputs.

(1) When double outputs (source/source) are in the discrepancy state (SA\Y0 and SA\Y1 are different), Y0 and Y1 are off.
(2) When double outputs (source/source) are on (SA\Y0 and SA\Y1 are on), Y0 and Y1 are on.
Setting method
Set the output wiring selection in "Wiring selection of output" from the "Parameter Processing of Device Station" window of the
engineering tool.
For the procedure to display the "Parameter Processing of Device Station" window, refer to the following.

Wiring selection of output Y
• When "Wiring selection of output" Yn is set to "0: Not used", output data is always off.
• When "Wiring selection of output" Yn (n: even number) is set to "1: Double wiring (Source/Source)", set
Yn+1, the partner of Yn, to "1: Double wiring (Source/Source)".
• For unused output terminals, set "0: Not used" in "Wiring selection of output".
