with dual LAN
Antaira Technologies
is a developer and supplier of device networking
and industrial communication products and is proud to introduce the
advanced version STE-708 and STE-716 Industrial Serial Device Server
series that encompasses device server network redundancy and zero
data loss redundancy feature solutions. Antaira Technologies’ new STE-
7xx series is a 1U 19” rackmount type designed serial-to-Ethernet device
server designed to transmit any standard serial RS232 or RS422/485 data
through the ubiquitousTCP/IP Ethernet based network.This series comes
with optional models supporting 8 (STE-708) or 16 (STE-716) serial COM
ports with 2,5 kV serial optical isolation protection for serial data.The new
STE-708 and STE-716 are embeddedwith dual independent IP address LAN
(10/100Tx) ports to support anymission critical applicationwith built-in dual
subnet mode to execute a data redundancy solution. The device servers
can also be connected directly to a redundancy network infrastructure by
accessing RSTP or ERPS ring protocol function. An LCM (Liquid Crystal
Monitor) is installed on the front panel of the unit that can be used to display
the unit information and perform basic configurations.This product series
has different optional models to support 100~240 Vac or 24/48 Vdc power
input and each model version provides extended operating temperature
support of -20° to 70° C.The STE-708 and STE-716 series can be configured
via a user-friendly web console,
windows utility software, or
Telnet command line through
the serial console (RS232 DB9
male) port in front of the unit.

james.liao@antaira.com.twSolution for pump protection
A range of electronic motor protection and control relays,
especially designed to protect pumps and motorsfrom a
variety of faults associated with this market is available from
NewElec
.The entire K series is aimed at rendering assistance
to pump users and consultants that specify protection require-
ments for pumps.What makes these relays unique is that they
incorporate features such as dry-run protection and phase
reversal protection which are basic requirements for the pro-
tection of pumps. A model exists for every budget.The more
upmarket models also include built-in features that allow for a
user-selected pump priming time, as well as a user-selectable
pump operating time slot.Automated re-start times for dry-run
trips are available together with selectable automatic overload
trip resets. A useful asset on some models permit the user to
measure dry-running conditions by means of power factor
measurements instead of conventional current measurement
so that greater accuracy can be achieved.The
range includes the most basic features that
need manual adjustments directly by the
user to the more sophisticated that can only
be programmed by the supporting software
avoiding possible setting interference by
users. These include the monitoring of sta-
tistical information such as the number of
starts, trip faults and pump efficiency. Motor
protection is achieved by the usual current
measurement methods and user-selectable
phase voltage.
