small in size but deliver bigfeatures; including 24V DCcontrol, communicationcapabilities, and expandedfunctionality.

See how many ways thesedevices can revolutionize theselection and use of whatwas once thought to bestandard control.

Lower Installed Costs

We’ve designed IT. to keepinstallation costs to aminimum. Small size, lessweight, modularity, removableterminal blocks, integrallywired solid-state controlcircuit components, completestarter assemblies, andcommunications capabilitiesto minimize point-to-pointwiring are just a few featuresthat keep overall costs down.

Low coil and overload relaypower consumption reducesenergy usage; and less heatgeneration eliminates orreduces control panel coolingand ventilation requirements.

24V DC Control

The Smartest and Safest

Choice in Power Today

Control with 24V DC isreliable, cost-efficient, globallyaccepted, and offers hugesafety advantages overtraditional AC control. Manyproducts ranging fromsensors to PLCs to valvemanifolds have alreadychanged to 24V DC power.

By incorporating 24V DCcontrol, we’ve reduced therisk inherent to working with higher control voltages.Other safety features includeguarded terminals, an environ-mentally friendly design – nohazardous materials,Type 2Coordination, and “hold-open”continuity of service. ThroughIT., we’ve ensured a safe working environment for personnel.

Improved Process and

Application Management

Say goodbye to the days ofreactive management! We’ve made IT. smart withcommunication capabilities,status indication, diagnostics,

remote reset abilities, and selectable andprogrammable protectivefunctions that simplifytroubleshooting and maximizeproduction time. Monitoringapplication parameters, suchas thermal memory, phaseloss, current unbalance, and"time-to-reset," over acommunication networkenables proactivemanagement of processesand applications.

easily removed and wired without interfering with

power wire connections.

Sealed coil power is as littleas 21% of typical devices,enabling the use of smallerpower supplies. Reduceenergy consumption andminimize heat generation inthe electrical enclosure.Eliminate or reduce the needfor ventilation and cooling.

Long Life

IT. NEMA contactors havebeen rated for excellentelectrical life. Superiormechanical life is anotherbenefit of their small size. Ingeneral, mechanical life isinversely proportional tocontactor size due to thegreater mechanical poundingassociated with the increasedmass and armature closingspeeds of larger devices.

Brownout Protection

Reduce downtime and scrapmaterial costs due to sags inline voltage. When used withIT. Power Supplies, IT.

Contactors will remain closedfor at least 300 ms on voltageloss while fully loaded.

Easy to Wire

Even though they’re small,wiring is still easy. Terminalsare clearly marked. Powerterminal wiring is easy withbox lug pressure typeterminals for 2.5mm to 8mm(5/16in.) hex tools.

Maximum Flexibility

Modular design and fieldinstallable accessoriesmaximize inventory flexibilityand permit customization.

Small Size

IT. Contactors are the smalleston the market today. The small size is a result of theoptimized DC magnet systemand not due to reductions incontact size, current carryingparts, or electrical clearances.IT. Contactors require as littleas 31% of the panel area, andweigh as little as 17% ofequally rated devices. Buildsmaller, lighter machines andequipment by building smaller,lighter control panels toreduce material, shipping andhandling costs.
