Warrick 16C1A002 Liquid Level Control

The Warrick 16C1A002 Liquid Level Control is a rugged, microprocessor-based conductivity level sensor designed for industrial-grade performance in HVAC/R and steam applications. Engineered as a direct-acting general-purpose control board, this unit is widely utilized for critical pump-down drainage, low-water cutoff protection, and high-level alarm systems. It operates on a standard 120Vac supply voltage and features a high-reliability SPDT relay, offering both normally open and normally closed contacts rated for 10A resistive loads.

For technicians and contractors, the 16C1A002 stands out with its 26,000 ohm sensitivity, ensuring accurate detection across various conductive fluids without the risk of false triggering. The open-board design utilizes a 1/16" panel standoff mounting style and spade terminals, which significantly speeds up wiring in control cabinets. A built-in 2-second time delay on increasing level prevents rapid cycling, or "chattering," caused by turbulent liquid surfaces or waves, protecting downstream equipment like pumps and solenoid valves from premature wear.

• Precise Conductivity Detection: The 26,000 ohm sensitivity is factory-set for high-accuracy liquid level monitoring in boilers and sumps.
• Direct Acting Operation: Ideal for pump down applications where the relay energizes when the liquid reaches the probe.
• Field-Proven Reliability: Solid-state design with AC current sensing to minimize probe electrolysis and extend electrode life.
• Streamlined Installation: Compact open control board with spade terminals allows for fast integration into custom HVAC control panels.
• Anti-Chatter Integration: Integrated 2-second delay ensures stable relay output even in turbulent fluid environments.

Is this control suitable for pump-up/refill applications?
This specific model is the direct-acting version, typically used for pump down (drain) or high-level alarms. For pump-up (fill) logic, an inverse-acting model is often required, though specific wiring configurations can sometimes adapt SPDT relays depending on the system design.

What kind of probes should I use with the 16C1A002?
It is designed to work with all standard Warrick conductivity probes and fittings. Ensure your liquid conductivity falls within the 26,000 ohm range for optimal performance.

Does this board require a separate enclosure?
No, this is an open-board style control intended for mounting within an existing electrical panel or UL-listed enclosure via the included 1/16" standoffs.
