Typical Bilge Pump Wiring
 
 
 
Basic BW8 Connections
 
 
 
BW8 Connections
 
 
BW8 requires +12/24v at 3mA (monitoring) max 160mA
BW8 Inputs P1-P8 each require +12/24v max. 2.5mA (Bilge Pump running).
SW input requires +12/24v max 2.5mA (SW is powered “ON”).
Each alarm output (AL or AT) supplys a switched positive voltage at a max. 50mA, the output voltage is approx. 1.2v less than the DC Supply connected to BW8 +.
