The COBO31 replaces the older COBO20. And COBO 32 (178mm x 137mm) replaces the older COBO 10 (169mm x 132mm). (Please note that the COBO32PCB is slightly bigger in size. see wiring diagram)


The difference between COBO31 and COBO32 is that, COBO31 has a normally closed (NC) input for the photocell whereas COBO32 has a normally open (NO) input. Hydraulic doors can be wired to the COBO31/COBO32 cards. Hydraulic doors have overflow fluid limits which requires to disable the electronic limit switches. This is selectable by linking the limit switches. Limit switches are linked as factory defaults
