SMALL FORM-FActor soLID-STATE RELAYS
The new Termopto solidstate
family of relays offers
electrical isolation in the size
of a terminal block. They
function as both a terminal
block for signal connection
and a relay to separate signals,
all in one compact module
for space savings in the control cabinet. Sixty versions include
standard input voltages from 5-230 VAC and DC, with
three optional output voltages of 5–48 VDC and 0.1mA, 5
– 48 VDC and 0.5mA, or 24 – 230 VAC with 0.1mA.

RUGGED PRESSURE SEnsors
PS300 series pressure sensors
for hydraulic applications feature
a rugged, IP69K-rated
design to withstand harsh
environments. They measure
3 bar to 400 bar. Signals
are processed on the PS300’s
new pressure measuring cell,
and then digitally transferred to the sensor’s fully potted,
self-contained display. Switch point accuracy is 0.5% of the
full scale. They’re available in male or female 1/4 in. NPT or
G 1/4 in. thread versions, with digital or analog outputs.

SMART, ruGGED PositionER
Sitrans VP300 incorporates
the 2007 Nobel Prize-winning
GMR effect. This “giant
magnetoresistance” technology
is used for non-contact
position sensing of a linear or
rotary valve shaft. This eliminates
any mechanical wear or
complex interaction of couplings and levers between these
components. Sitrans VP300 requires only one magnet for
strokes up to 150 mm (5.9 in.) or rotary angles up to 120º. It
also features SIL-certified, partial-stroke testing (PST).

HEAVY-DUTY SLURRY KNIFE GATE VALVE
Series DX Slurry Knife gate
valve is designed especially
for heavy slurry applications
in the power and mining industries.
When it opens, reinforced
elastomer sleeves seal
against each other and provide
a 100% full-port opening,
minimizing turbulence, which in turn minimizes wear.
The seats isolate and protect all metal parts from coming
in contact with the process. When the valve is closed, the
sleeves provide a drop-tight seal. It also provides drop-tight
shut-off in both directions.

LOW-MAINTENANCE, HIGH-AccurACY pH/ORP SEnsors
The new S651CD submersible
electrode and S656CD
insertion electrode combine
superior performance
with lower maintenance requirements
and longer life.
S651CD is an upgrade to
the original S650CD. It can
replace the S650CD and S650CDHT, and is designed
for measurements in tanks, flumes and sewer lines. The
S656CD is an upgrade to the S656CD electrode, and can
be used in place of the S655CD, S655CDHT and 970283
models.

REALLY cooL 60W POWER suPPLIES
These 60W power supplies
offer either a standard operating
temperature range
or one with an extended
low range down to -40°C.
They have universal, widerange
input, up to 89.7% efficiency,
no-load losses less
than 0.45W and large screw terminals that accept up to 10
AWG wire. They are NEC Class 2-approved. The standard
version has a temperature range of -10 °C to +60 °C. Both
ranges come in a 12-15 VDC or 24-28 VDC adjustable output
voltages.
