Broyce Control B8LCR Level Control Relay 110VAC

The Broyce Control B8LCR Level Control Relay is a compact, 110 VAC liquid level controller designed for conductive liquids, using an 8‑pin plug‑in base to monitor a single probe and drive a changeover (SPDT) output. It supports selectable “Pump Up” or “Pump Down” operation, with adjustable sensitivity from 5 to 100 kΩ and a low‑voltage AC current across the probes to prevent electrolysis phenomena; the unit is part of a family that includes the 11‑pin B1LCR for two‑probe operation. When using a metal tank, connect pin 1 to the tank, and expect a compact enclosure roughly 89 mm high × 40 mm wide × 92 mm deep, rated for ambient temperatures from −20 to +60°C and up to 95% relative humidity; supply variants across 24, 110, 230 or 400 VAC are offered, with 110 VAC as the model here.
