AccuTrace™ Multizone Heat Trace Control Panel

Valin’s AccuTrace™ control panel incorporates the latest technology and is packed with features designed to help optimize your heat trace system.

The AccuTrace™ panel utilizes PID algorithms designed to maintain temperature in the most challenging applications, for both ambient sensing and line sensing. The panel has 30-amp Solid State Relay controls and GFEP (30mA) trip protection. a multitude of alarms, including high temp, low temp, high current, low current, sensor failure and Ground Fault Equipment Protection, creating a package of unrivaled performance.

For extreme cold starts and long circuit lengths, the AccuTrace™ panel employs a soft start feature, reducing the inrush current. This helps mitigate potential high current alarms that are a known problem during startups.

The AccuTrace™ multiloop has a 10”, full color, easy-tonavigate touch screen display. The control interface is intuitive and simple to program, allowing for fast, accurate setup and commissioning. We also offer 3 levels of password protection, to further ensure the highest security while allowing quick access in the field, as appropriate.
