Interface board for the DS1603NF ultrasonic liquid sensor. Powers the sensor and provides a 12V output under normal condition and a grounded output under low fuel alarm condition.
Wiring: From the main bus, connect a fused wire to the “12V” pad, connect panel ground to the “GND” pad, connect a momentary pushbutton switch between the “PTT” pad and ground, and connect the “OUT” pad to an EFIS alarm input.
BILL OF MATERIALS:
C1: Vishay K104K15X7RF5TL2 0.1uF 50V X7R Radial Ceramic Capacitor
C2: TDK Corp. FG14X7R1E475KRT06 4.7uF 25V X7R Radial Ceramic Capacitor
J1: JST S4B-XH-A-1(LF)(SN) 4-Position 2.5mm Right Angle Shrouded Header
Q1: Microchip TN2106N3-G 60V 300mA N-Channel MOSFET, TO-92-3
R1-R2: Stackpole RNMF14FTC4K70 4.7k-Ohm 1/4W 1% Axial Resistor
S1: Pushbutton Switch, Normally Open, Momentary Type (Installer’s Choice)
