JUMO dTRON 316 304 308
Compact Temperature Controller Jumo Dtron 316
The JUMO dTRON 316 controller is made up of four freely programmable devices in different DIN formats, for the control of temperatures, pressures and other process variables. The high-contrast, multi-coloured LCD screen for actual value, set-point and user management consists of two four-position 7 segment readouts, two one-position 16 segment readouts, display of the active set-point, six switch setting indicators and displays showing units, ramp function and manual operation.
Easy to operate through four buttons. The device can be used as a two-point, three-point, three-point stepping controller or constant controller.
Common features: Four programmable setpoints, two parameter sets · Program function with eight sections or ramp function · Maximum of four limit comparators · Two timer functions · Two self optimizing experience · Fast friendly configuration with setup program and program editor.

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. The electrical connection is made at the back, via screw terminals. The possible input and output configurations are shown in the following block diagram. The option boards are universally applicable for all instruments in the series.
