The soft start feature is selectable which
allows this controller to be employed in nonheat
trace applications as well.
All process conditions may be monitored
and managed both locally and remotely. All
process variable, communication and alarm
settings and security codes are user-adjustable
via simple page menu navigation.
In terms of system supervision, the ITC
controller monitors temperature, current load
and ground fault equipment protection leakage
current (GFEP). Additionally, the alarms
on the ITC consist of high and low temperature,
high and low current, high GFEP current
and sensor failure.
Should the ITC unit realize a failed sensor,
the controller automatically switches into a
user adjustable manual output duty cycle. To
eliminate abrupt current spikes, the Chromalox
ITC employs bumpless transfer power
switching when switching over from either
manual or auto mode.
The ITC unit is housed in a compact 10” x
8” x 6” (26cm x 21cm x 15cm) wall mountable,
NEMA 4X FG enclosure and it features
a high resolution TFT display, LED indication
of Load, Power & Alarm status for each
circuit and front panel capacitive touch user
interface buttons which are mounted on a
The ITC enclosure provides electrical connections
for the heating cable, the AC Power and
the RTD Sensors and it comes complete with
stainless steel mounting brackets.
The Chromalox intelliTRACE ITC series is designed
for line or ambient sensing heat trace
applications such as freeze protection and/or
process temperature control. This controller
may be used with constant wattage, mineral
insulated or self regulating heating cables.
The ITC is intended for use in industrial locations
in either hazardous (Class I, Division 2)
or non-hazardous environments.
The ITC Series is offered in either a single
circuit or an independently controlled and
monitored dual circuit platform. They provide
a unique, industry-leading combination of
heating capacity, application flexibility and
The ITC is a microprocessor based system
with SSR (Solid State Relay) power control
which switches an impressive 40 Amps per
circuit at 100-277 VAC.
There are three user-selectable control modes
available on the ITC: Manual, Off or Auto. An
output of 1% to 100% is available while in
Manual Mode and you may choose either PID
or ON/OFF control while in the Auto Control
You may employ one or two RTD sensors for
either circuit. When using two RTD sensors,
the ITC may be set to Low, High or Average.
The ITC may also be used as a 2-channel
ambient sensing controller that uses only 1
RTD to control both circuits. This provides the
owner with much more flexibility and redundancy
to help meet their ever-varying process
The ITC employs a soft start feature that
uses a proprietary software algorithm which
eliminates the inherent self-regulating in-rush
current, resulting in longer circuit lengths and
less nuisance tripping at cold temperatures.
