Application hints:
SECU-DATA instruments which are to be installed in Ex-zone 1 have to be
supplied from an intrinsically safe power supply to ensure the ignition pro-
tection as per ATEX (directive 94/9/EC) EN 60079-0, and EN 60079-11.
The not intrinsically safe power supply with a permissible voltage range of
18 … 36 V is connected to the input IN of the barrier SECU-BAR 125.
SECU-BAR 125 limits the output voltage to max. 25.2 V and the output
current to max. 131.3 mA. The intrinsically safe output OUT is connected to
the power supply terminals of a SECU-DATA xxxx device.
