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 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 Fiberglass 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 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 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 Mode.
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 demands.
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.
