The Rosemount 3490 Controller provides comprehensive control functionality for 4–20 mA or HART compatible transmitters, such as the Rosemount 1208 Level and Flow Transmitter. The Rosemount 3490 consist of two models, 3490A and 3490C. The Rosemount 3490 Controller enables simple programming for level and flow measurement to control pumps, totalize flows, log data and calculate differentials. The controller is easy-to-read and has a colored LCD display that offers a simple, intuitive and an user-centric interface.

The Rosemount 3490 Controller is part of Rosemount’s water and wastewater portfolio, designed to accompany the Rosemount 1208 Level and Flow Transmitters. To match these water and wastewater applications, the controller can be field mounted on either walls or pipes, as well as having a weather protection cover for increased screen visibility and an extra degree of protection in the worst outdoor environments. Process performance is optimized by local control and automation through monitored measurement values, totalization, pump control, and calculated variables such as open channel flow measurements. The Rosemount 3490 also allows you to log measured values, easily accessible and shareable through a webserver. Up to two sensor inputs are available for connection of any 4-20 mA or HART transmitter. To gain full pump operations control, level measurement metrics is used by controlling pumps or alarms through up to six output relays. Although the controller has been developed specifically for the water and wastewater industry, its versatile functionalities make it applicable within other industries where 4-20 mA or HART transmitters are used.

The Rosemount 3490 is equipped with step-by-step wizards to guide the user through configuration and setup for the most common applications. The application wizards provide various configuration possibilities and options, such as level measurement, pump control, and flow calculations. All measurements can be totalized, differenced, logged, to then be displayed on the display. The following application wizards are available: Level and pump control, Open channel flow, Differential level, and Tank volume.

The controller’s user interface has a simple and intuitive design, including a colored LCD display and physical keypad buttons to navigate through the software application. The display serves as an interface for the user to visualize measured values and status of inputs and outputs.

The Ethernet port can be used for Modbus TCP/IP connection to host systems. By simply connecting the controller to the existing LAN network, communication over Ethernet is established. Logged data is easily shared through the controller web interface.
