Mk8 O2 Interface

This module enables O2 trim with Mini Mk8 and Mk8 MM Controllers for limited budget applications. We generally recommend the Mk8 EGA EVO instead, as it enables a more advanced 3 parameter trim.

O2 interface setup

The default configuration for inputs and output 1 is 4-20mA, (0-10Vdc can also be used).

Inputs 2 and 3 are set to 150C and 20C as default, (4-20mA or 0-10Vdc can also be used).

Analogue Input 1 – O2 Signal Input

Analogue Input 2 – Stack Temperature Input

Analogue Input 3 – Inlet Temperature Input

Analogue Output 1 – Firing Rate Output
