Rosemount 3490 Series

2-2

Transmitter input

The Control Unit will accept input from a 4-20mA / HART transmitter.
Model 3492 will accept inputs from two HART transmitters.

NOTE

The Rosemount 3490 Series is designed for non-hazardous (safe) area
installation, but can be connected to a transmitter installed in a hazardous
area. For certifications of the Control Unit, see Appendix B.

Control functionality

Control functionality is provided by five SPCO voltage-free contact relays in
the control unit. There is also an isolated 4-20mA signal output.

For applications where the functionality of the control unit is linked to other
external events, the two digital input ports will accept contact closure signals.

Front Panel

The Rosemount 3490 Series is programmed simply using the 6-button
membrane keypad on the front panel. Menu structured programming is
employed, with the display assisting the user with dynamic help text.

A full specification for the control unit is in Appendix A.
