The JUMO dTRON 300 series of controllers includes four freely programmable instruments in different DIN formats for controlling temperature, pressure and other process variables. The high-contrast, multicolor LC display or 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, 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.
