Safety Instructions
The most important safety instructions are summarised in this
section. They supplement the corresponding regulations which
the personnel in charge must study. When working in hazardous
areas, safety of the personnel and plant depends on complying
with all relevant safety regulations. Assembly and maintenance
staff working on installations therefore have particular
responsibility.
A precise knowledge of the applicable standards and regulations
is required.
✗
the national safety, accident prevention, assembly and
installation regulations (e.g. IEC/EN 60079-14)
✗
generally recognised technical regulations,
✗
the safety instructions and information of this document,
characteristic values of the type labels and the instruction
plates
✗
the EC Type Examination Certificate (according to ATEX) or
conformity or partial certificate (after previous approval) and
special conditions contained in it
✗
that any damage may render explosion protection null and
void.
✗
that for use in Zone 1 or 2 the DOMV must be installed into
an enclosure certified acc. to IEC/EN 60079-0 and for use in
Zone 21 or 22 into a enclosure certified acc. to
IEC/EN 61241-1
✗
that for installation into an enclosure a suitable pressure
release device must be provided (e.g. screw-in silencer by
Legris)

Use the component in accordance with its designated use and for
its intended purpose only (see chapter "Function/
Characteristics"). Incorrect and impermissible use or non-
compliance with this document invalidates our warranty

Function/Characteristics
The digital output module with valve (DOMV) is a system
component of the Remote I/O system IS1 for actuation of
pneumatic control circuits. The module is snapped directly onto
the BusRail of the IS1 system and connected via BusRail to the
power supply and the internal data and address bus.
The DOMV is an intrinsically safe equipment with degree of
protection Ex ib for installation in hazardous areas of Zone 1.
The output circuits are implemented as pneumatic control
circuits.
The modules are equipped with an additional Ex i digital input for
simultaneous disconnection of all module outputs ("Outputs
OFF"). It complies with the requirements of the functional safety
according to IEC 61508 up to SIL2.
