Chromalox: Digital Heat Trace Controller

These single or independently controlled and monitored dual-circuit microprocessor-based temperature controllers switch 40 Amps per circuit at 100-277 VAC, and may be used in either freeze protection or process temperature control applications. The compact 10 x 8 x 6-inch NEMA 4X enclosure facilitates all of the electrical connections including the heating cable, the AC Power and the RTD Sensors. The unit features a high resolution TFT display, PID or On/Off SSR control, selectable soft start program, dual RTD sensor input per circuit, current load and GFEP monitoring. All process variables may be monitored both locally and remotely, and all alarm, communication and system settings are user-adjustable via simple page menu navigation. The unit has manual, on/off or auto control modes. An output of 1% to 100% is available while in manual mode and the user may choose either PID or on/off control while in the auto control mode. When using two RTD sensors, the controller may be set to Low, High or Average. This provides flexibility, as well as redundancy, to help meet varying process demands.
