Mains-powered BL 513 standard signal isolator
The BL 513 standard signal isolator and
amplifier from Knick’s BasicLine series is
a high-end yet very affordable device for
reliable signal conversion and transmission
in common applica-tions. It features reli-
able galvanic three-port isolation of input,
output, and auxiliary power supply, which
prevents measurement errors or distortion.
The BL 513 range is designed for a
300 Vac/dc working voltage and supports
easy handling.The calibrated range selec-
tion function makes manual adjustments
unnecessary. Furthermore, DIP switches
allow for easy configuration while being
protected against accidental changes.
Thanks to an integrated wide-range power
supply the isolator can be operated both
with 24Vdc supplies and 100 230Vac mains
supplies. The BL 513 is CE-compliant and
UL-certified. Knick provides a three-year
warranty for the device. Strictly concen-
trating on basic functions, leaving all
extras aside, Knick has tailored BasicLine
devices to mechanical engineering com-
panies that need precise and reliable yet
cost-optimised isolators for large-scale
applications. Notwithstanding the attractive
price scheme, the devices feature Knick’s
characteristic high level of manufacturing
quality and precision as well as complete
galvanic isolation. BasicLine comprises
transducers for all major control cabinet
requirements: Current, voltage, or tempera-
ture measurement, conversion of standard
signals or measured values, signal isola-
tion, and set-point monitoring.

New relays make safety simpler
With just three models, safety relays in the new G9SR range
from Omron cover virtually all common control system safety
requirements in standalone applications. With built-in intel-
ligence that maximises their flexibility, the new relays feature
front-panel DIP switches for fast, easy configuration and cus-
tomisation, together with LED indicators for at-a-glance status
monitoring and fault diagnosis.
Key characteristics of the new safety relay modules include
certification to category PLe in line with EN/ISO 13849-1, fast
response time to ensure minimum stopping times, solid-state
outputs for long-life wear-free operation, compact housings
to save space in control panels and removable spring-type
terminals to ensure rapid straightforward installation. All units
are equipped with an additional monitoring output to provide
diagnostic information for use by the standard control system.
The basic unit in the G9SR family is just 17,5 mm wide and
has single- or double-channel safety inputs, plus double-
channel solid-state safety outputs. The outputs are rated at
2 A, which makes them suitable for direct switching of even
large contactors.
Complementing the basic unit is the advanced unit, which is
22,5 mmwide and has single- or double-channel safety inputs
plus double-channel safety relay outputs rated at 5 A. For ap-
plications where input expansion is needed, each advanced
unit can control up to two G9SR basic units that are configured
as additional safety inputs to the same safety function.

Rugged cellular router offers
Broadband wireless connectivity
Siemens Ruggedcom RX1400 is a multiprotocol intelligent
node which combines Ethernet switching, routing and fire-
wall functionality with variousWAN connectivity options.The
device is IP40 rated, does not use fans for cooling, operates
continuously within a -40 °C to +85 °C temperature range and
comes with a rugged metal housing that supports DIN rail,
panel, or rack mounting.The Ruggedcom RX1400 provides a
high level of immunity to electromagnetic interference, heavy
electrical surges, extreme temperature and humidity for reli-
able operation in harsh environments. The integrated GNSS
(GPS/GLONASS) functionality allows the device to report its
location as necessary for asset tracking purposes in large scale
deployments.
The Ruggedcom RX1400 is designed to support primary
communications over commercial LTE networks and leverage
LTE’s enhanced capabilities for QoS (Quality of Service) man-
agement. For reliability purposes the device is able to rollback
to 2G and 3G wireless connectivity. In addition the cellular
router is equipped with a Dual SIM card slot which enables
automatic failover in case of interruption in the communication.
The device can also be used with two optional small form factor
pluggable fibre optic transceivers (SFPs), to establish wireline
communication in areas where fibre is available.
