11.3 Ex "d" / Ex "ib" / Ex "n" design for VT42/ST42
and VR42/SR42 (4 ... 20 mA / HART)
Important
The devices may only be operated in explosive areas if the
housing covers have been fully closed.

1) Supply power terminals 31 / 32
a) Ex ib:
Ui
= 28 V DC
b) Ex d [ib] / Ex nA [L]
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 [L]:
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.
