Industrial LLC14A1A F12-D Liquid Level Control

SSAC's LLC14A1A F12‑D is a single‑probe liquid level control in the LLC1 family that detects conductive liquids via a submerged probe and switches a load when the level is reached. It provides ON/OFF control with a built‑in time delay to prevent rapid cycling and wear on pumps and relays. The device offers two contact configurations: non‑isolated SPST and isolated SPDT, enabling direct pump or valve control or interface with a control system. A low‑voltage sense between probe and common is isolated from the main input and output circuits, simplifying wiring and reducing interference. Common applications include turning pumps on to maintain a set liquid level, providing overflow protection, and acting as an inexpensive level switch in tanks and reservoirs across general industrial settings.
