Description
The JUMO di 308 display instrument displays temperatures in °C or °F and unit signals in "plain text".
The basic unit is already equipped with an analogue input, two binary inputs, two relay outputs, two logic outputs and a power supply for two-wire transmitters. Three expansion slots can be equipped with additional inputs and outputs and interfaces. The high-contrast, multi-color LCD display for the measured value display and operator guidance consists of a five-digit 7-segment display (value display or parameter setting), an eight-digit 16-segment display with color switching (value display, parameter name, channel name, process/alarm text as max. 24-character scrolling text or pseudo bar graph) and four switching position displays for the binary outputs.
Four device buttons and optionally a setup PC program are available for operating and configuring the device (e.g. Configuration of maths and logic functions, input of display texts).
The linearizations of the usual encoders are stored; a customer-specific linearization can be configured with 10 interpolation points or via the coefficient input of the polynomial.
The devices can be integrated into a data network via an interface (RS422/485 or PROFIBUS-DP). The electrical connection is made at the back via screw terminals.
