2x MOSFET high-current outputs are available. These have built-in reverse diodes against the external supply voltage and are therefore particularly suitable for switching inductive loads (relays) that are operated with supply voltage.

14 pcs. Outputs. These are universal outputs that switch to ground via a ULN2003 (CMOS Version) driver. The pull-up resistors are connected to a selectable voltage via jumpers. If you want a pure open collector output without pull-up, these resistors are not fitted.

CAUTION: because of a layout error OUT11 and OUT13 must NOT be used (short circuit at U1 pin 4 and 6). A manual correction of the lines is possible.
