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.
