The JUMO dTRON family of modular PID profile controllers is capable of 2-state, 3-state, modulating, or continuous control. An 8-step ramp and soak profile capability is standard on each unit. Being modular, the dTRON can be configured to match your specific needs: multiple analog inputs, multiple analog and relay outputs – including a solid-state relay option, RS422/485 communication, supply for 2-wire transmitters, a math and logic module, auto-tuning, alarms, timers, and ratio/humidity/differential controllers are all available. The dTRON Plast controller specifically designed for the plastics industry (extruders, injection molding, hot channel runners) is available along with compatible temperature and pressure sensors.
The JUMO dTRON 300 series of controllers includes four freely programmable devices in different DIN formats for controlling temperature, pressure and other process variables. As a temperature controller (TR) according to EN 14597 the devices are used in heat-generating plants to control the temperature of liquids or gases (mode of action: 1B). The high-contrast, multicolor LC display for process value, setpoint and operator prompting contains two four-digit 7-segment displays, two single-character 16-segment displays, display of the active setpoints, six switch position indicators, and displays for the dimensional unit, ramp function and manual operation. Simple operation through 4 keys. The instruments can be used as 2-state, 3-state, modulating or continuous controllers.
The controller software includes a program or ramp function, parameter set changeover, two autotuning (self-optimization) procedures, a math and logic module, as well as 4 limit comparators. Linearizations for the usual transducers are stored, and a customer-specific linearization table can be programmed. A setup program is available for user-friendly configuration from a PC. A serial interface for RS422/485 or Profibus-DP can be used to integrate the instruments into a data network.
