Remote I/O IS1+ as an
edge gateway for Zones 1 and 2
Alongside its proven remote input/
output (I/O) functionality, IS1+ (photo)
is now also available for use as an
edge gateway with a connection via
OPC UA and optional integrated signal
pre-processing. In this process,
all diagnostics and device data are
transmitted parallel to the supported
communication protocols Profibus
DP, ProfiNet, EtherNet/IP or Modbus
TCP via OPC UA to superordinate
systems, such as aggregation servers
or cloud applications. This means that
IS1+ can be used in modern system
concepts such as NAMUR Open Architecture
(NOA) for monitoring and
optimization functions using the second
channel, and enables the use of
these concepts in hazardous areas
in Zone 1. For brownfield systems in
particular, which often operate using
Profibus DP, IS1+ offers a simple migration
path: While process control
is still performed via Profibus, all additionally
available data from the system
and connected field devices is
transmitted via a second channel with
Ethernet and OPC UA. - R. Stahl,

Certify cables with this
hand-held device
The new WireXpert 500 cable tester
(photo) targets copper cabling up to
Cat 6A standards. With its modular
concept and unique licensing system,
the WireXpert 500 is a versatile,
cost-effective tool for cable system
certification in office environments,
industrial
UL-rated pressure switches for
explosive environments
The new 703-U and 703-UJ Series
of UL-rated, explosion-proof pressure
switches (photo) are suitable
for gaseous or liquid fluid systems
in hazardous applications, including
offshore exploration, petrochemical
processing and oil-and-gas pipelines.
The 703-U and 703-UJ Series
have a corrosion-resistant stainlesssteel
construction and UL ratings
for hazardous locations, including
Class 1: Division 1, Groups A, B, C,
D, as well as Class 2: Groups E, F,
G. Units also feature high overpressure
capabilities, a NEMA Type 7 explosion-proof
rating and rugged piston
design, enabling these switches
to withstand high pressure spikes,
shock and vibration. The 703-U/UJ
Series cover a pressure range: from
6 to 5,000 psi and a temperature
range of -40 to 180°F. - SigmaNetics,

settings, laboratories and
data centers. By enabling cable certification
up to Cat 6A only, the WireXpert
500 fits over 95% of contractor
requirements. Contractors can also
easily upgrade WireXpert 500 units to
certify copper cabling through Cat 8
or fiber optic cabling. The device features
the Dual Control System, which
equips both local and remote devices
with a main processor and color LCD
screen. These features reduce the
amount of walking a single user must
do during troubleshooting, improving
the testing efficiency for smaller, oneperson
testing projects. - Softing
