  • Power: the lambda requires a DC power supply with 12V and at least 1.5A
  • Power connector: it has two wires: Brown=GND, Yellow=12V
  • Output: the controller provides an extension cable with a 6 pin connector for the SPx DAQs, it can be connected to Lambda 1 / AN1 or Lambda 2 / AN2 connectors.
  • SP6: In the case of the SP6 it is necessary to add either an intermediate connector or just remove the 6 pin connector to use the “screw-type” connector
