The MS-2100 Series temperature controllers are designed for single-point (MS-2101), or dual point (MS-2102) heat trace control in stand-alone heat trace applications. Based on pipe temperature, MS-2100 Series controllers continuously monitor all your important variables, including heater current and ground fault levels.


MS2100 series controllers offer full Master Trace functionality in a compact, field-ready, easy to install package.

  • Features On/Off controls, with "deadband" that can beadjusted based on the parameters you require.
  • Offers Proportional Control (where the heater is only partially turned on), in order to maximize the unit's performance and reliability.
  • Provides master override input for load shedding or ambient temperature override.
  • Uses the PowerLimit and StaggerStart features to reduce high inrush current and eliminate the need for over-sized breakers.
  • Periodically checks your circuits using TraceCheck, alerting you to potential problems even on circuits that aren't in use.
  • Independent Ground Fault Alarm and Ground Fault Trip
  • Inherent RS-485 Modbus communication capability

  • Networks with other MasterTrace controllers to provide you with a flexible, cost-effective solution.
  • Alerts you to problems before they occur, avoiding frozen pipes or process problems.
  • Saves you money by logging minimum and maximum values and energy usage.
  • Comes ready-to-install in a rugged NEMA-4X rated enclosure with no field assembly required.
  • Provides you with maximum reliability and minimum vulnerability in the event of hardware failure.
