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.
Applicable solid state
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 Off time: 0.5ms or less
