Warrick 16DMB1A0 Level Control Relay

For industrial fluid management, the Warrick 16DMB1A0 Level Control Relay is the reliable professional choice for 120V conductivity-based liquid level control. This 11-pin octal plug-in module belongs to the high-performance 16DM series, specifically engineered with DPDT (Double Pole Double Throw) contacts. By integrating these DPDT load contacts, you eliminate the need for secondary slave relays, reducing panel complexity and total footprint. With a 10K ohm sensitivity and direct mode operation, this module provides precise, microprocessor-controlled monitoring for pump down or single-level high-level alarm applications.

Designed for the rigors of the field, the 16DMB1A0 features solid-state reliability and a 12 VAC secondary probe voltage to minimize electrolysis on sensing electrodes. This module is rated for 5A resistive at 120/240VAC, making it a robust interface for industrial solenoid valves and motor starters. Its standard 11-pin octal socket mounting ensures rapid replacement in HVACR systems, wastewater treatment, and process cooling loops, handling ambient temperatures up to 150°F.

Key Benefits

• Internal DPDT Contacts: Features 2 NO and 2 NC contacts (5A 1/10 HP rating), removing the requirement for external slave relays.
• 10K Ohm Sensitivity: Optimized for standard water-based applications, providing stable point level detection without false triggering from foam or steam.
• Direct Mode Logic: Ideal for pump down service or high-level failsafes where the relay energizes upon liquid contact.
• Modular 11-Pin Base: Simplifies installation and troubleshooting in compact control panels using standard 11-pin octal sockets.
• LED Diagnostics: Integrated LED monitoring provides immediate visual confirmation of the relay state during commissioning.

Common Questions

Can the 16DMB1A0 be used for pump up (fill) applications?
This specific model is factory-set for direct mode, typically used for pump down or high alarms. For pump up applications, an inverse mode module or external logic inversion via the DPDT contacts is required.

Does this module require a specific electrode type?
It is designed to work with any Warrick conductivity-based probe or float switch, as long as the liquid’s resistance is below the 10K ohm threshold.

Is an 11-pin socket included with the relay?
The 16DMB1A0 is a plug-in module; the 11-pin octal socket is a separate accessory often found in existing panel assemblies or available for new installs.
