Warrick 16DMC1M0 Level Relay Control

The Warrick 16DMC1M0 is a field-proven 120V DPDT level relay control designed for high-reliability liquid level monitoring in HVACR and industrial pump applications. As part of the respected Series 16DM, this conductive liquid level controller features a 26K Ohm sensitivity factory setting, making it the ideal choice for sensing standard tap water, condensate, or boiler feed water. Its Double Pole Double Throw (DPDT) contact configuration provides two sets of isolated 5-amp resistive contacts, allowing technicians to manage both a primary load and an auxiliary alarm or signal circuit simultaneously without the need for additional slave relays.

Built as a compact solid-state plug-in module, the 16DMC1M0 utilizes an 11-pin octal plug for rapid installation and simplified field replacement. This specific unit operates in Direct Mode, where the relay energizes when liquid reaches the high probe and de-energizes when the level falls below the probe (or low probe in differential service). The circuitry is housed in a durable clear Lexan enclosure, enabling clear visibility of the LED status indicator for real-time troubleshooting on the jobsight. By utilizing a 12 VAC secondary voltage on the probes, it ensures safe execution and minimizes electrolysis, extending the operational life of the sensing electrodes in single-level or differential service.

• DPDT Contact Design: Eliminates the need for external relays by providing two independent 5A contacts for simultaneous pump and alarm control.
• 26,000 Ohm Sensitivity: Optimized for mid-range conductivity, ensuring precise detection in condensate tanks and cooling towers.
• Direct Acting Operation: Simplifies logic for 11-pin octal configurations, often used for pump-down or high-level cut-off applications.
• Plug-In Portability: Standard 11-pin base allows for "hot-swapping" the module during maintenance, reducing system downtime.
• Internal LED Monitoring: Provides immediate visual confirmation of the relay state to assist in rapid diagnostics.

What base is required for the Warrick 16DMC1M0?
This is an 11-pin octal plug-in module. It requires a standard 11-pin socket, typically the Warrick 11-pin base, which is sold separately for panel or DIN rail mounting.

Can I use this for non-conductive liquids like oil or distilled water?
No, this unit is a conductivity-based control. It requires a conductive medium. For low-conductivity fluids or oils, a float-style switch or a higher-sensitivity HM series relay would be required.

Is the sensitivity adjustable on this specific model?
The 16DMC1M0 is a factory-set 26K Ohm module. If the fluid conductivity changes significantly, you must ensure the resistance of the liquid remains below 26,000 Ohms for the probe circuit to complete successfully.
