IntelliTrace Commercial Controller

The Chromalox intelliTRACE CTC is a microprocessor based system with SSR power control that switches 40 Amps per circuit at 120-277 VAC. The CTC is a single or dual point commercial heating cable controller with integrated ground-fault protection. This controller may be used with CZH, CMi or CPR heating cables. The CTC is intended for use in commercial nonhazardous applications.

There are three user-selectable control modes available on the CTC: 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 Mode.

You may employ one or two RTD sensors per circuit. When using two RTD sensors, the CTC may be set to Low, High or Average. The CTC may also be configured as a 2-circuit ambient sensing controller that uses only one RTD to control both circuits. This provides the owner with much more flexibility and redundancy to help meet their ever-varying demands.

The CTC employs a soft start feature that uses a proprietary software algorithm which reduces the inherent self-regulating in-rush current, resulting in 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.

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 CTC controller monitors temperature, current load and ground fault equipment protection leakage current (GFEP). Additionally, the alarms on the CTC consist of high and low temperature, high and low current, high GFEP current and sensor failure.

Should the CTC unit realize a failed sensor, the controller automatically switches into a user adjustable manual output duty cycle. To eliminate abrupt current spikes, the Chromalox CTC employs bumpless transfer power switching when switching over from either manual or auto mode.

The CTC unit is housed in a compact wall mountable, NEMA 4X FG or optional 316 SS 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 hinged door.

The CTC enclosure provides electrical connections for the heating cable, the AC Power and the RTD Sensors and it comes complete with stainless steel mounting brackets.
