S2R Sensor Multiplexer Interface

SCAD’s S2R-quad converts the output of SCAD’s popular electronic tank level sensors to a standard variable resistance up to 240 Ohm output. The S2R enables SCAD’s sensors to integrate with standard float sensor inputs on digital vehicle and vessel monitoring and switching systems such as the Victron Cerbo GX (not intended for use with analog float sensor gauges).


Note: SCAD sensors are designed for use with SCAD monitors, which pulses regulated power to the sensor periodically. Powering SCAD sensors by other means may result in damage to the sensor or inconsistent readings.

Features

  • Periodically reads and stores tank level from up to four SCAD sensors
  • Outputs variable resistance up to 240 Ohm (similar to American float sensor type output)
  • Automatically calibrates SCAD sensor for empty and full values (requires one empty-full tank level cycle)
  • Optional custom calibration service for OEM customers
  • 12 to 30 volts DC power
  • Connector plugs provided
