E-138
Switching output
circuits
(terminals 5-, 6+ and
7-, 8+) Models 830 X S2 and 830 X S1
for connection to an intrinsical-
ly safe circuit each with linear
characteristic and the following
maximum values:
Ui = 60 V
Ii = 150 mA
Pi = 350 mW,
temperature classes T6 and T5
Pi = 700 mW,
temperature class T4
Effective internal capacitance
Ci ≤ 12 nF
The effective internal inductance
is negligibly small.
Equipotential bonding
(PA)
for connection to the equipoten-
tial bonding system
The switching output circuits are safely galvanically isolated
from each other and against the input current loop up to a
crest value of the nominal voltage of 60 V.
CAUTION!
The sum of the voltages of the connected intrin-
sically safe circuits must not exceed 60 V.
A voltage may be ignored if it is less than 20 % of
the other voltage.
