1) Supply power terminals 31 / 32
a) Ex ib:
Ui
= 28 V DC
b) Ex d [ib] / Ex nA [nL] UB
= 14 … 46 V DC
2) Switching output, terminals 41/ 42
The switching output (passive) is designed as an optocoupler. If
required, the switching output (passive) can be designed as a
NAMUR contact (to DIN 19234).
a) NAMUR with switching amplifier
b) Switching output (optocoupler)
- Ex ib:
Ui
= 15 V
- Ex d [ib] / Ex nA [nL]:
UB
= 16 … 30 V
IB
= 2 … 15 mA
Important
Supply current (supply power) and switching output must be
either only intrinsically safe or only non-intrinsically safe. A
combination of the two is not permitted. On intrinsically safe
circuits, equipotential bonding must be in place along the
entire length of the cable used.
