Compact Controllers  Manufacturers, Traders, Suppliers

The JUMO dTRON 3xx 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 14 597 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, three-step 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 user-friendly configuration from a PC. The devices can be
integrated in a data network through a RS422/485 or PROFIBUS-DP
interface. The electrical connection occurs at the back with screw
terminals. The block diagram displays the possible input and output
configurations. The option boards are universally applicable for all
devices in the series.
