The Littelfuse SSAC LLC44A1F1 is a single-probe conductive liquid level control for 120 V AC in an octal plug-in package. It runs the pump down to drain the tank from a single probe. A factory-fixed 1 second time delay keeps the output from cycling on a moving surface.
Single-probe level maintenance: resistance sensing with a solid-state time delay that keeps the output from cycling rapidly. Isolated 12 V AC at the probe prevents electrolysis; a trickle current under 1 mA senses liquid between the probe and common. It also works with low-voltage resistance-changing transducers, for temperature limits and similar controls.
Sensitivity: fixed at 1K ohms (±10%). Probe voltage: 12 V AC, isolated. Output: 4 A resistive at 240 V AC; 1/10 hp at 240 V AC; isolated SPDT. Supply tolerance: -20% / +10% of nominal; 50/60 Hz.
It plugs into an octal 8-pin socket. It operates from -20 to +60 °C and stores from -40 to +80 °C.
