Warrick 16MA1A0 Level Control

The Warrick 16MA1A0 Level Control is a rugged, solid-state plug-in module engineered for high-reliability liquid level sensing in industrial and HVACR environments. Designed for direct mode operation, this 120 VAC liquid level controller features a fixed sensitivity of 4.7 K ohms, making it a precise solution for monitoring conductive liquids in differential service or single-level service applications. Housed in a durable, clear Lexan octal plug-in enclosure, the 16MA1A0 utilizes a microprocessor-based design to ensure stable performance and resistance to nuisance tripping caused by surface turbulence or sloshing. The unit facilitates easy field service with its 8-pin octal socket and screw terminal connections. Rated for 10 Amp resistive loads and 1/3 HP at 120/240 VAC, the Warrick 16M series simplifies the management of condensate pumps, hydropneumatic tanks, and industrial sump systems. Its wide operating temperature range of -40°F to 150°F ensures consistent automation control in demanding plant conditions.

• Enhanced Circuit Stability: Microprocessor-controlled logic filters out electrical noise and physical liquid turbulence for accurate level detection.
• Rapid Field Installation: The 8-pin plug-in design allows for fast replacement and minimizes downtime during maintenance cycles.
• Versatile Control Logic: Supports both pump-up and pump-down configurations when paired with the appropriate conductivity probes.
• Industrial Grading: Features UL Motor Controller listing and SPDT (1 Normally Open, 1 Normally Closed) non-powered contacts for broad compatibility.
• Safe Low-Voltage Sensing: Uses a 12 VAC RMS secondary circuit on the probes to minimize electrolysis and extend electrode life.

What is the sensitivity of the Warrick 16MA1A0?
This specific model is factory-set to 4.7 K ohms sensitivity, ideal for general-purpose water and mildly acidic liquid level sensing.

Does this module require a specific socket?
Yes, the 16MA1A0 is a plug-in module that requires a standard 8-pin octal socket with screw terminals for proper electrical termination.

Can I use this for differential level control?
The 16MA1A0 supports differential service (maintaining levels between two points) using three probes: high, low, and a reference/ground probe.
