The OCB301 is a programmable Bargraph with 30 Bar Segments. It is designed for panel mount for connection to analogue signals and permit visualizing of the measured process. The three colours can be free distributed across the entire bar length. The intensity of the bar can be set between 20% and 100% to permit visibility under different lighting conditions.

Firm Signal Ranges 2V, 5V, 10V, 0-20mA and 4-20mA at two inputs are pre-calibrated. The range of the bar 0-100% can also individually be assigned to other signal values such as 4,2mA – 19,6mA. There is no necessity of using external calibrators for setting any range.

Separate versions are available for PT100 and PT1000 resistance thermometer.

The parameters are entered by using three keys behind the front lens. The menu contains selection of the input signal, assigning the input signal to the bar length, selection of the colours and settings of two Set Point Relays.

The Bargraphs are supplied from 18-36VDC and can be used for horizontal or vertical mount. Also the reading direction from left to right or down to up can be selected.
