Aux outputs

There are three aux outputs.

  • Aux 1 a low-side output, i.e. it switches to ground. Maximum current 3A.
  • Aux 2 a low-side output, i.e. it switches to ground. Maximum current 3A.
  • Aux 3 a high-side output, i.e. it switches to positive. Maximum current 6A.

The Aux 3 output can directly drive reverse-light bulbs, without any additional relay.

The source for the Aux 1 and Aux 2 outputs is the ground on pin B8 GROUND. Under a higher load on these outputs, the ground wire running to pin B8 GROUND must have a sufficiently large cross-section, 1.5 mm² (16 AWG) recommended.

The source for the Aux 3 output is the positive on pin C8 +12V CONST. Under a higher load on this output, the positive wire running to pin C8 +12V CONST must have a sufficiently large cross-section, 1.5 mm² (16 AWG) recommended.

One of the available options for the aux outputs is a fully configurable PWM table. It can run in variable-frequency, variable-duty-cycle, or on/off mode - the last one is available by selecting Variable duty cycle and entering a frequency of 0 Hz. Thanks to the configurable data sources on both axes, the table can also act as a simple logic output, e.g. enabling the output only when one value is greater or smaller than the other. Example use: driving an additional transmission oil cooler fan. The Rescale axis option lets you set any table size from 2x2 to 16x16.
