Functions & Features

• Accepts direct input from an RTD and provides

a standard 4 – 20 mA DC signal

• Linearization and burnout

• Wide operating temperature range suitable for

harsh environments

INPUT SPECIFICATIONS

Maximum leadwire resistance: 20 Ω per wire (3-wire)

Sensing current: 1 mA

Temperature range

Typical Applications

°C: 0 – 50, 0 – 100, 0 – 150, 0 – 200, 0 – 300,

0 – 400, 0 – 500, 0 – 650

• Mounting in a sensor connection head minimizes noise

effect and signal degradation
