t2000 Series Electronic heat-tracing controller Product Overview /COMMUNICATIONS INTERACE CARRIER REQ TO SEND The DigiTrace heat trace controller is designed to provide the benefits associated with single point controllers in a multi-point configuration. By taking advantage of innovative modular packaging techniques, single point controllers are inserted into a rack assembly as circuits are required. Individual circuits can easily be locked out or changed without affecting other circuits. Most importantly, all circuits can be independently monitored simultaneously without scrolling or calling up individual circuit functions. Isolated wiring configurations allow the controllers to be powered with 90 to 240 Vac, while mechanical contactors or solid-state relays allow circuit switching up to 60 amps at 600 Vac with single- or three-phase power. Two RTD sensor inputs for each controller make possible a variety of combinations of temperature control, monitoring, and alarming. The is available with two output types: an electromechanical relay (EMR) or a solid-state relay (SSR). Systems can be configured for nonhazardous and hazardous areas. Controller interrogation is available both locally and remotely, and configurable with or without supervisory software. Control The measures temperatures with 3-wire, 100 ohm platinum RTDs connected directly to the unit. The controller may be used in line sensing, ambient sensing, proportional ambient sensing, and power limiting modes. Monitoring Up to 21 control parameters can be measured including voltage, ground fault, temperature, and current variables to ensure system integrity. The system can be set to periodically check the heating cable for faults, alerting maintenance personnel of a pending heat-tracing problem, and avoid costly downtime. A dry contact relay can be provided for alarm annunciation back to a Distributed Control System (DCS). THERMAL MANAGEMENT SOLUTIONS EN-DigiTraceseries-DS-H /13 1 / 6 t2000 Series Ground-fault protection National electrical codes require ground-fault equipment protection on all heat-tracing circuits. Heat-tracing circuits equipped with DigiTrace controllers do not require additional ground-fault detection equipment, simplifying installation and reducing costs. Installation The controller includes LED displays that make it easy to view alarm conditions and programming settings. Settings are stored in nonvolatile memory in the event of power failure. Communications The units may be networked to a host PC running Windows -based DigiTrace Supervisor software for central programming, status review, and alarm annunciation. DigiTrace units support the Modbus protocol and are available with an RS-485 or 10Base-T Ethernet communication interface. Packaging The is mounted into control racks in prefabricated panels with each control rack designed to hold up to 10 controllers. Multiple racks in panels can accommodate up to 120 circuits. Any unused spaces in a rack are pre-wired for insertion of controllers to allow for expansion of the system.

Outputs open on alarm or loss of power. Each controller may be configured to alarm on high or low temperature, voltage, load current and/or other alarm conditions at user preset levels. The also monitors the integrity of the RTD sensors and, by means of groundfault protection, the integrity of the heat-tracing cable and power distribution system. Separate ground-fault alarm and trip points may be set with the ability to display and document actual ground-fault levels. As required by the NEC for EPD devices, both legs are broken by means of a DPST switch for ground fault interruption.
