Space-saving Two-wire Signal
Conditioners B3-UNIT

RTD TRANSMITTER
(field-configurable)

Functions & Features
• Converts a RTD input into an isolated, linearized 4 – 20 mA DC signal
• DIP switch configurable input range
• Linearization and burnout
• Monitor terminals
• High-density mounting

MODEL: B3FR[1]

ORDERING INFORMATION
• Code number: B3FR[1]
Specify a code from below for [1].
  (e.g. B3FR/UL/Q)
• Input range (e.g. Pt 100 0 – 200°C)
• If you need the transmitter to be calibrated to a specific range, please specify when ordering.
Non-specified orders will be shipped at default factory setting (Pt 100 0 – 100°C).
