This compact digital heat-trace controller offers versatility
The new ITC Series intelliTRACE controller is designed for line- or ambient-sensing heat trace applications in hazardous (Class I, Division 2) or non-hazardous areas. Available in single- and dual-circuit models, the ITC features a high-resolution display and may be used in either freeze-protection or process-control temperature applications monitoring all process variables both locally and remotely. The ITC is a microprocessor-based system with solid-state-relay power control, selectable soft-start program, current load, dual resistance-temperature-detectors (RTD) sensor input for each circuit, and ground fault equipment-protection monitoring. There are three user-selectable control modes available on the ITC: manual, off or auto. The ITC’s compact enclosure facilitates electrical connections for the heating cable, the a.c. power, and the RTD sensors. This controller may be used with constant wattage, mineral-insulated or self-regulating heat-trace cables. — Chromalox, Inc., Pittsburgh, Pa.
