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.
The soft start feature is selectable which allows this controller to be employed in non-heat trace applications as well.
Remote monitoring and management is accomplished through several communication choices such as Modbus RTU/RS485 or RS422, which is standard, or Modbus TCP/Ethernet, Webserver/Ethernet or BACnet/Ethernet, which are optional.
