●Safety input monitor outputs: Y4 to Y11
Safety input monitor outputs are used to output the status of safety inputs in SafetyOne.
Intended outputs
(Terminal names) Target safety inputs
(Terminal names) Description of operation
Safety input 1 monitor output
(Y4) Safety input 1
(X0-T0, X1-T1)
Safety input 2 monitor output
(Y5) Safety input 2
(X2-T2, X3-T3)
Safety input 3 monitor output
(Y6) Safety input 3
(X4-T4, X5-T5)
Safety input 4 monitor output
(Y7) Safety input 4
(X6, X7)
Safety input 5 monitor output
(Y10) Safety input 5
(X10, X11)
Safety input 6 monitor output
(Y11) Safety input 6
(X12, X13)
When the target safety input is ON,
the monitor output is ON. When the
target safety input is OFF, the monitor
output is OFF.
Note. When the targeted safety input detects an input monitor error, input circuit failure, or EMC the
disturbance, corresponding safety input monitor output becomes a pulse output (1Hz). The
monitor output is OFF in other errors, Initial state, or Configuration state.
●Safety output monitor outputs: Y12 and Y13
Safety output monitor outputs are used to output status of safety outputs in SafetyOne.
Intended outputs
(Terminal names) Target safety outputs
(Terminal names) Description of operation
Safety output 1 monitor output
(Y12) Safety output 1
(Y0, Y1)
Safety output 2 monitor output
(Y13) Safety output 2
(Y2, Y3)
When the target safety output is ON,
the monitor output is ON. When the
target safety output is OFF, this
function is OFF. The monitor output
turns OFF immediately, independent
of the preset OFF-delay time.
Note. When the safety output detects an output circuit failure, the corresponding safety output monitor
output becomes a pulse output (1Hz). The monitor output is OFF in other errors, Initial state, or
Configuration state.
●State monitor outputs: Y14 to Y16
State monitor outputs are used to output the internal state of SafetyOne.

each state.
Warning
The monitor outputs are not safety outputs. Do not use these to construct a safety system.
