The
CR5395
Series of
DC Current Sensing Relays
are designed to provide a
contact output that becomes active when the setpoint DC Current is reached. Similar
to the CR4395, this product includes adjustable activation delay, adjustable setpoint,
and choice of output styles. An important feature of this design is the use of a mag-
netic modulator to detect the magnetic fields generated by current in the conductor.
This enables the use of torroid current transformer technology that inherently rejects
the effects of outside magnetic influences. Hall effects and other types of technolo-
gies must be on-site calibrated to adjust for stray magnetic fields present in most in-
dustrial applications.
The
CR4395
Series of
AC Current Sensing Relays
are designed to provide a
contact output that becomes active when the setpoint AC Current is reached. Avail-
able in active high or active low, this relay is a fully featured product, with an ad-
justable activation delay, adjustable setpoint, dry contact relay or solid state outputs,
and remote sensing capabilities.
The
CR3395
and
CR3495
Process Alarms
are products that can be added
to standard analog process signals and create alarms and level indication. Ad-
justable time delays, various power supplies, current ranges, and sensor configura-
tions are available.
The
CR9300
,
CR9400, CR9500
and
CR9600
Current Switches
and Sensors
are go/no-go proving switches that are self powered with solid state
dry contact modeled outputs. Output styles are designed to provide the highest cur-
rent switching capability possible at the lowest possible switchpoint. Normally closed
and normally open logic are available.
Sensing Relays and Switches
CR Magnetics Sensing Relays and Switches provide a simple method of monitoring electrical properties and alerting a system to
a fault or event condition. These products are available with a wide variety of configurations, including time delays, various output
styles and logic. From simple proving switches, to fully featured high performance ground fault sensing, our relays and switches will
provide the designer with the tools needed to implement many different control and event sensing schemes.
Sensing Relays and Switches
The
CR7310
Ground Fault Sensor
provides an easy method in realizing
equipment AC ground fault protection. Using the same footprint as our other fully
featured products, the
CR7310
can sense currents down to 10 mAAC and up to
100 AAC. Various power supplies, current ranges, and sensor configurations are
available.
