Warrick 16B1D0R Level Control Refrigerant Built with a NEMA 2The Warrick 16B1D0R Level Control is a rugged, conductive liquid level controller designed for industrial high demand environments. This open circuit board control features a 120 VAC primary supply and is factory configured for direct acting mode, meaning the load relay energizes when the liquid reaches the high probe. Utilizing solid state reliability, the 16B1D0R provides a 10,000 ohm sensitivity rating, making it the standard for general purpose
