Jumper Settings
The NetAXS-123 Controller Board provides two jumper sets, one each for output relay 1 and output
relay 3. Each relay has two 3-pin jumpers associated with it. One jumper selects either external power
(EXT) or self-whetted (on-board, +12V) power to be applied to the relay contact load. The other
jumper is used to select Normally Open (NO) or Normally Closed (NC) relay contacts. There is a total
of four 3-pin jumpers (two per relay) on the Controller Board.

Each relay is associated with two jumpers. As shown below, a relay’s left jumper configures the relay’s
load source (12VDC or External), and the right relay jumper configures the relay contact type
(Normally Closed or Normally Open).
