Non-Incendive parameters:

max

= DC 10 ... 30 V, I

max

= 30 mA (Note 2)

Ci = 11 nF (+0.3 nF/m with cable), Li = 10 µH (+2 µH/m with cable)

Notes

1. The non-incendive eld wiring concept allows the interconnection of two devices with non-incendive parameters not

specically examined in combination as a system when: Uo or Voc ≤ V
