The OCB778 is a bargraph from Orbit Controls with 48 segments and five digits high resolution display designed for both Analogue Process Signals and Digital Serial Ports inputs.

For Analogue process signals, Pt-100 and Thermocouples can be directly measured with 16 bit resolution whilst Serial Ports RS232 or RS485 have selectable Baud Rate up to 115200 bd.

The type of input signal, setting of parameters, display resolution and scaling are Menu selectable and can be free programmed using the keys behind the front lens.

For Control Applications the OC778 offers Two Set Points with Transistor or Relay outputs.

Whilst in the measuring mode the display shows the input signal, and in programming mode the display shows the parameters.
