JUMO dTRON 300 - Compact Controller (703041)

The JUMO dTRON 300 controller series consists of four freely programmable devices in various DIN formats to control temperatures, pressures, and other process variables. The devices are used as temperature controllers TR according to DIN EN 14597 in heat generating plants for the control of temperatures in fluid and gas mediums. The high-contrast, multicolor LCD display for the actual value, setpoint value, and operator guidance consists of two four-digit seven-segment displays, two single-digit 16-segment displays, display of active setpoint values, six relay status indications, and display for unit, ramp function, and manual mode. Simple operation with four keys. The devices can be used as 2-state, 3-state, 3-state modulating controllers, or continuous controllers. Among others, the controller software includes a program or ramp function, a parameter block switch, two self-optimizing methods, one math and logic module, and four limit value monitors. The linearizations of the common measuring probes are stored; programming of a customer-specific linearization table is possible. A setup program is available for the convenient configuration with a PC. The devices can be integrated in a data network through a RS422/485 or PROFIBUS-DP interface. The electrical connection takes place at the back using screw terminals. The following block diagram displays the possible input and output configurations. The option boards are universally applicable for all devices in the series.
