Red ETI Tracon GPT 230
The GPT 230 Dual Channel Heat–Trace Control is a dual–point microprocessor–based heat–trace control thermostat. It is ideal for applications which require two independent heater–control Channels with Ground–Fault Equipment Protection (GFEP). Ideal uses include freeze protection, hot water temperature maintenance, grease line trace, tank heating, and other temperature monitoring and control applications.
- Adjustable Temperature Setpoint and Alarms Sensor Inputs
- Precision Monitoring and Control
- Ground–Fault Equipment Protection
- Automatic GFEP Circuit Self–Test
