Orbit Controls OC7520 is a programmable display for connection to parallel BCD data

ports. It is designed as a remote display for digital meters, programmable controllers,

printers etc. In the measuring mode the 6 digit display shows the data from the port. In the

programming mode the display shows the parameters.

By using the RS Option card, OC7520 can very simply convert the BCD parallel input data

into RS232/RS485 serial data output. The serial port parameters such as the Number of

Digits, Display Resolution, Baud Rate, Address, Continuous or Request Transmission and

the Termination of the data string can be programmed from the keyboard.

Analog Output is an option, which permits generation of 0/4…20mA or 0 …±10V from the

BCD parallel input data shown at the display. The output of 12 bits (4096 increments) can

be free assigned to any two display values. The Analog Output is isolated from the Inputs

and the supply.

Four Set Points can be programmed within the entire display range 0 ... ±999999. They

activate four open collector NPN transistors or four mechanical relays.

The keyboard at the front permits the entry into the menu, setting of RS232 and Analogue

Output parameters as well as setting of the Set Points.

The menu contains 6 digits offset free adjustable which permits the data from the Bus to

be added or subtracted from the offset.

The display intensity can be adjusted in 7 steps with the keys UP or DOWN.

Isolated excitation for supplying of external sensors is available. The parameters are

stored in internal memory also when the power is switched-off. The instrument is supplied

from the mains or from DC voltage and is suitable for panel mount.

(with build-in options RS232 and Analogue output)

Software Version 7520_V5.hex CS: 1120

The menu will be opened with the key MENU. With the same key the submenu will scroll

at the display. The required parameter will be confirmed with ACK. Its value will be set

with UP or DOWN. The flashing digit - Cursor - will be positioned with ACK. The sign and

the decimal point can be set when the flashing display is positioned outside of the display

(no digit flashing). The decimal point will be adjusted with UP, the sign with DOWN.
