Approvals

The electronic temperature controller PTM-2000 is an eight-channel temperature monitoring and four-channel control device. PTM-2000 controller is used as a part of various electric heating cable systems and ensures optimal temperature maintenance for each channel. The algorithms used for heating control, in combination with a wide range of different sensor types, ensure optimum control of the heat tracing and saves energy.

The temperature control will be realized by using processing signals received from temperature, precipitation and water sensors. The PTM-2000 can be integrated into computerized process control systems via data transmission interface RS485 or MOD_BUS/RTU. The heating control is effected by means of output relay channels. All operating parameters and conditions of the connected heating systems are displayed with a display. The PTM-2000 controller is designed to be mounted on a DIN rail 35 mm in control cabinets.

  • 8 temperature measuring channels
  • 4 independent control channels
  • Excellent Accuracy
  • High interference immunity of measurement channels
  • Digit matrix display with white backlight
  • Simultaneous display of temperatures and heating status for 4 channels
  • Temperature setting range from −100 °C to +600 °C
  • Easy adjustment of controlled temperatures
  • DIN-rail mounting
  • Communication interface RS485, MOD_BUS/RTU
  • The preset parameters are saved in nonvolatile device memory
