)/0.022 A
Ʋ Example - with U
B
= 24 V DC
(24 V - 12 V)/0.022 A = 545 Ω
Overvoltage protection
Dielectric strength against metallic
mounting parts
> 10 kV
Overvoltage resistance (test impulse
voltages 1.2/50 µs at 42 Ω)
> 1000 V
Additional overvoltage arrester
Due to the floating structure of the electronics and com-
prehensive insulation measures generally not necessary.
Electrical protective measures
Potential separation
Electronics potential free up to 500 V AC
Protection rating
IP66/IP68 (3 bar, 24 h) acc. to IEC 60529,
Type 6P acc. to UL 50
Altitude above sea level
5000 m (16404 ft)
Protection class
III
Pollution degree
