OCB501-A is a digital controller with one bargraph and a three digit display. The controller is key programmable and permits connection to analogue process signals, Pt 100 and DIN Thermocouples with or without junction compensation. The intensity of the displays can be set between 0 and 100% in 1% steps or controlled with external analogue signal (Option). Additional signal channel can optionally be ordered for arithmetic operations of two processed signals:
DISPLAY = Coef 0+ADC1*Coef 1+ADC2*Coef 2, whereas Coef are free programmable Constants and ADC are the measured values.
The bargraph and the Digital Display are free scalable. The digital display permits a resolution of 999 counts with selectable decimal point. In the measuring mode the display follows the input data. In the programming mode it shows the parameters. Floating point arithmetic is used.
Menu is accessible with three keys behind the front lens and contains the setting of four Set Points, Colours of the Bargraph, Scaling of the Digital Display and the Bargraph and Calibration of signal channels.
Set Points SP1 and SP2 define the switching points of the Bargraph colors and also of the Relay 1 and Relay 2. The colour sections red, green or orange can be set across the entire bargraph length. Additional Set Points SP3 and SP4 control Relays 3 and 4.
