Analog Inputs

The UNIPRO allows for three analog inputs with their individual functions determined by "daughter board" located on the analog input board inside the unit. The standard connection, at TBD, will have the first input as a thermocouple, the second for the oxygen probe, and the third optionally used to input voltage or milliamp signals.

Analog Outputs

Two, separate, isolated analog outputs are provided on TBD and can be selected as 4-20 mV (for maximum accuracy, see Specifications for further details) or 0-10 V output through DIP switch settings on the analog output board. Additionally, outputs can be calibrated by placing a jumper on the two terminals supplied.

DIP Switch Setup

The user may use the UNIPRO in a multi-instrument system by giving the instrument a unique HOST address, specified by using the DIP switches on the Interface Board inside the UNIPRO

To get to the DIP switches, loosen the black knurled knob on the front panel by turning in a counterclockwise direction. Carefully remove the front panel but DO NOT remove the ribbon cable connecting the front panel to the Interface Board. Safely support the front panel near the instrument. Adjust the DIP switches per Section 2.16 for the desired operating mode. When switch adjustment is complete, replace the front panel to prevent contamination.
