Relay Switches on the Rosemount 4051S Pressure Transmitter | Emerson
1:58
The Rosemount 4051S Pressure Transmitter supports two integral high voltage, high current independent relay switches built right into the transmitter. These pressure switches can provide enhanced asset protection and maintain system safety by preventing overpressure conditions. Because the switches are integrated into the transmitter, you can expect the same Rosemount pressure transmitter reliability and diagnostics, reducing failure and accuracy issues that can happen with stand-alone switches. The Rosemount 4051S relay switch can be used in a wide variety of pressure, differential pressure flow, and differential pressure level applications including overfill prevention in tanks by controlling pumps or valves, controlling heat tracing based on the module temperature, or maintaining pressure levels by activating a pump when the pressure changes.
