Product Description

Product Description

Product Overview 

With the Rosemount 333 HART Tri-Loop Signal Converter, you can easily obtain up to three additional analog outputs. This signal converter is designed to convert a digital HART multivariable signal into three independent 4-20 mA analog process variables without additional transmitters and wiring. Available as a high-alarm or low-alarm device, this product also offers DIN rail mount options and electrically isolated analog output channels for flexible configurations.

 Description

The 333U is engineered to convert signals among multiple loops, facilitating the integration of various field devices. With its support for the HART (Highway Addressable Remote Transmitter) protocol, it can communicate digitally over the same pair of wires that carry the 4 - 20 mA analog signal. This feature allows for enhanced functionality, such as remote configuration, calibration, and diagnostic capabilities.

The Rosemount 333U offers high - accuracy signal conversion, with typical accuracy levels within a very small tolerance range. This ensures that the converted signals accurately represent the original process variables, minimizing errors in the control system.

The device provides loop isolation between the input and output loops. This isolation helps to protect the control system from electrical interference and ground loops, which can cause inaccurate measurements and control problems. By isolating the loops, the 333U ensures the integrity of the signals and the reliable operation of the overall system.
