The new IntelliTRACE system is a complete control solution designed for heat trace applications, such as process temperature maintenance, freeze protection and roof/gutter de-icing. The modular design of the control panels and components allows users to select only features needed for their specific heat trace installation, thereby minimizing the purchase price and simplifying system configuration. This single-channel system uses microprocessor-based control and comes completely pre-wired and assembled, with a variety of options that include three different AC line voltages (120, 240 and 277), RS-485 communications interface, and Ground Fault Indicator.
Installation, start-up and use of the units are further simplified with easily programmed standard features. Three control modes are available: ON/OFF, PID and SMART tuning. The temperature alarm can be programmed for process deviation, band, high/low and latching/non-latching (manual or automatic reset). The low current alarm can be set from 0 to 30 A in 1 A increments. The optional GFI alarm trip can be adjusted over a range from 5 mA to 100 mA. The dual digital display can be programmed for either ºC or ºF.
All systems are designed for universal inputs, which include types J, K, L, N, R and S thermocouples, RTDs, current and voltage. Each unit comes in a NEMA 4X glass fiber reinforced enclosure (12.5"H x 10.5"W x 6"D) that includes a solid-state relay with 30 A rating at 40 ºC, mounted on a heatsink, and a current transformer to measure operating current. The optional GFI modules have a shutdown contactor and illuminated reset switch. A terminal block is used for field connections on all units.
