GENERAL DESCRIPTION

CTS Series Transducers are self-powered, solid-state current-operated

switches that trigger when the current level sensed through the aperature

exceeds the adjusted setpoint. The solid state output contacts can switch AC or

DC; this “universal” output makes them well suited for application in

automation systems.

CTS Series Current Operated Switches combine a current transformer, signal

conditioner and limit alarm into a single package for use in status monitoring or

proof of operation applications. Offering an extended setpoint range of 1-150 A

and universal, solid-state outputs, the self-powered CTS can be tailored to

provide accurate and dependable digital indication of over-current conditions

across a broad range of applications. Available in solid-core enclosure styles or

in a split-core case to maximize ease of installation.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the

literature or on equipment must be observed to ensure personal safety and to

prevent damage to either the instrument or equipment connected to it. If

equipment is used in a manner not specified by the manufacturer, the protection

provided by the equipment may be impaired.

Do not use this unit to directly command motors, valves, or other actuators

not equipped with safeguards. To do so, can be potentially harmful to persons or

equipment in the event of a fault to the unit.
