Wiring specifications
Cable length Note2 100m maximum (total wiring length per 1 input)
Allowable wiring resistance 300Ω maximum
Note1. The drive port generates check pulses in order to diagnose input devices and internal
circuits. (Wiring and the diagnostic function are different depending on the logic selected.
See “Chapter 5 LOGIC” for details. But the basic function is same.)
Note2. For cables longer than 30m between SafetyOne and connected devices, or wiring drive
terminals and receive terminals separately, use grounded shielded cables to assure
electromagnetic compatibility.
