Tracon GPT 230

Dual Channel heat trace TEMPERATURE CONTROLLER

The GPT 230 Dual Channel Temperature Controller is ideal for applications which required two independent heater zones.  Each zone has it’s own relay and GFEP.  Any 3 wire RTD or Thermistor sensor can be used for temperature sensing. Any 100k ohms 3-wire RTD or Thermistor sensor can be used for temperature sensing.

  • Adjustable Temperature Setpoint and Alarms Sensor Inputs
  • Precision Monitoring and Control
  • Ground–Fault Equipment Protection
  • Automatic GFEP Circuit Self–Test

FEATURES

  • Dual channel heat trace capabilities allows for complete control and monitoring of two separate channels from one unit
  • Adjustable temperature setpoint allows precise control of a wide range of processes
  • Can use an NEC Class 2 temperature sensors with up to 2,000 ft. cable for enhanced installation options
  • Two Thermistor temperature sensors with 20 ft. cables included for applications of −40 °F to 230 °F (−40 °C to 110 °C)
  • RTD input allows higher accuracy and extreme–temperature applications
  • The unit can accommodate RTD sensors with 3–wire configuration
  • Temperature display for accurate adjusting and monitoring
  • Load current display for accurate adjusting and monitoring
  • Ground fault current display for accurate monitoring, protection, and alarm
  • Adjustable alarm thresholds for excess ground fault current, load current, and temperature
  • Alarms indicated with panel display and relay contact for remote signaling
  • A Fault Mode setting which can be set to energize or de-energize the heaters during a sensor failure
  • Fire Protection Mode maintains heater operation for use in critical fire protection systems
  • Durable weather–resistant NEMA 4X IP66 enclosure permits indoor or outdoor installation
