z  Make sure that the end-user thoroughly understands the contents of this user’s manual. 
Note 1. SafetyOne reads input data at regular intervals. Use a solid state output device that sends 
output signals of the waveforms shown below. Otherwise the SafetyOne cannot process the input 
signal correctly.

output device 
Pulse output off cycle of 40ms or 
more and an off time of 1ms or less.
Pulse output off time of 0.5ms or 
less. 
(Waveform of solid sate 
output) 
The device may not be usable even if the above specifications are satisfied. Be sure to 
thoroughly confirm operations using the actual device. 
Off cycle: 40ms or more 
Off time:   
1ms or less
