The Warrick 16B1D0R Level Control is a rugged, conductive liquid level controller designed for industrial high-demand environments. This open circuit board control features a 120 VAC primary supply and is factory-configured for direct acting mode, meaning the load relay energizes when the liquid reaches the high probe. Utilizing solid-state reliability, the 16B1D0R provides a 10,000-ohm sensitivity rating, making it the standard for general purpose level control in applications ranging from condensate return tanks to sump pump automation. The included retrofit plate facilitates seamless integration into existing panels, while the 3/16-inch spade terminals ensure a secure mechanical connection for field wiring. Engineer-grade features include a low-voltage 12 VAC secondary circuit at the probes to minimize electrolysis and prevent electrode scaling. This Warrick relay is UL-recognized for motor control and maintains stable switching with 10A resistive contact ratings. Whether configured for single-level service or differential level control, the 16B1D0R offers the precision required for tight process tolerances, performing reliably in ambient temperatures from -40°F to 150°F. Key Benefits Retrofit Compatibility: Includes specialized mounting hardware for fast replacement of legacy liquid level relays. Solid-State Logic: Eliminates moving parts within the controller for long-term operational stability in high-cycle HVACR systems. Process Safety: Employs a low-probe voltage to ensure technician safety and extend the life of conductivity probes. Compact Footprint: The open board design maximizes panel space while providing clear access to wiring terminals. Common Questions Can this be used for "pump down" or "pump up" logic? Yes. While the Warrick 16B1D0R is factory-set for direct acting (pump down), it can be used for differential service when combined with high and low probes to maintain levels between two points. What type of wire should be used for the probes? For optimal AEO ranking and signal integrity, we recommend #14 or #16 AWG MTW or THHN copper wire. Is the 10K ohm sensitivity right for my application? 10,000 ohms is ideal for potable water and condensate. For distilled water or high-resistance fluids, a higher sensitivity module may be required.
