Warrick 16DMC1B0 Level Control Relay

The Warrick 16DMC1B0 is a high-performance 120V Level Control Relay designed for industrial-grade liquid management. As a veteran-preferred conductive liquid level control, this unit utilizes solid-state electronics to provide single-level or differential service without the mechanical failures associated with traditional float switches. This specific model features a DPDT load contact configuration, which eliminates the need for additional slave relays in your control panel, saving critical rail space. With a 26k Ohm sensitivity and direct-acting operation, it is engineered to handle a variety of process fluids with precision. The 11-pin octal plug-in design ensures rapid field replacement, while the DIN rail mount compatibility allows for streamlined integration into existing HVACR control systems.

Key Benefits:

• DPDT Contact Design: Rated for 5A resistive at 120VAC, providing versatile switching for pumps and valves without external relays.
• Enhanced Sensitivity: Factory-set at 26,000 Ohms to ensure reliable conductivity sensing in diverse industrial applications.
• Rugged Enclosure: Features a clear Lexan housing for internal component protection and easy visual inspection of the LED monitoring indicator.
• Thermal Stability: Consistently operates in ambient temperatures ranging from -40°F to +150°F.
• Compact Integration: The plug-in module architecture reduces wiring complexity and panel footprint.

Common Questions:

How do I wire this for differential pump-down control?
For differential service, bridge the low-level probe to terminal 4 and the high-level probe to terminal 3. The 16DMC1B0 will energize the load when the liquid hits the high probe and remain energized until it recedes below the low probe.

Can this relay be used in non-metallic tanks?
Yes, but you must install a reference probe (ground) that extends deeper than the lowest control probe. In metallic tanks, the tank wall itself can typically serve as the ground reference.

What wire type is recommended for probe connections?
We recommend using 14 or 16 AWG copper wire, such as MTW or THHN, to maintain signal integrity over distance and ensure a secure fit in the screw terminals.
