Rosemount 248RAI5Q4GR Temperature Transmitter

The Rosemount 248RAI5Q4GR Temperature Transmitter is a rail-mount, single-input device in Emerson’s Rosemount 248 family that converts sensor signals to a standard 4-20 mA current with digital HART communication. It accepts one input from RTD sensors (2-, 3-, or 4-wire), thermocouples, millivolts, or resistance (ohm) sensors, enabling flexible integration with a wide range of temperature sensors. The Q4 option provides a calibration certificate for traceable calibration, and the transmitter supports NAMUR-compliant diagnostics (NE21, NE43, NE44, NE89, NE107) for health and status visibility in the field. Designed for DIN rail installations, this model delivers a robust rail-mount solution with a 4-20 mA/HART output for reliable process monitoring and instrumentation networks.
