Warrick-Gems Sensors & Controls 16MC1A0 Liquid Level Control Module

Description

The Warrick-Gems Sensors & Controls 16MC1A0 is a general-purpose, plug-in liquid level control module engineered for reliable, direct-acting liquid level sensing in a wide range of commercial and industrial HVAC and hydronic applications. Its compact, enclosure-free design allows for straightforward installation into a standard 8-pin octal relay socket, making replacement and field servicing fast and efficient.

How It Works

Operating in Direct Acting mode, the 16MC1A0 energizes or de-energizes its output relay in direct response to liquid level changes detected through the sensing circuit. When liquid bridges the probe gap, the conductivity of the fluid completes the circuit and triggers the relay — providing precise, dependable level control without mechanical float components.
