The supply voltage (L+...L–) is to be connected
between Pin 1 and Pin 3 on the plug. The nominal
voltage is 24 V DC. This voltage is allowed, as per
EN 61131<2, to fluctuate between 19.2 V and 30 V
with 5 % residual ripple.
The supply voltage must comply with SELV as per
EN 60 950-1.
For application and usage as per the requirements of
cULus, the supply voltage must be provided by a trans-
former with protected secondary. A safe industrial
power supply unit with overcurrent protection is to be
used. In case of error 60 V DC may not be exceeded.
The following applies to cylindrical sensors:
a) either max. 5 A for voltages from 0 ... 20 Vrms
(0 ... 28.3 Vp)
b) or 100/Vp for voltages from 20 ... 30 Vrms
(28.3 ... 42.4 Vp).
