The Littelfuse SSAC LLC14B1AX is a single-probe conductive liquid level control for 120 V AC on a conformal-coated open board. It runs the pump to fill the tank from a single probe. A factory-fixed 1 second time delay keeps the output from cycling on a moving surface.
A single-probe level control with a built-in time delay that keeps the output relay from cycling rapidly. Isolated low-voltage AC at the probe prevents electrolysis; a trickle current under 1 mA senses liquid between the probe and common. Conformal-coated open board for OEM equipment and commercial appliances.
Sensitivity: adjustable up to 250K ohms, to ignore foam and floating debris. Probe voltage: low-voltage AC, isolated from input and output. Output: 10 A resistive at 120/240 V AC and 28 V DC; 1/3 hp at 120/240 V AC; non-isolated SPST and isolated SPDT contacts. Supply tolerance: -20% / +10% of nominal; 50/60 Hz.
It mounts on nylon standoffs, with 0.250 in (6.3 mm) male quick-connect terminals. It operates from -20 to +55 °C and stores from -40 to +80 °C.
