User Guide

Notes:

1. To achieve full specifications input voltage must be within ± 10% of nominal.

2. Floating (non-grounded) or grounded input signal may be used.

3. To change from 4 - 20mA to 1 - 5mA remove R3. To convert to 10 - 50mA add a 150Ω 1W resistor across

terminals “5” and “6.” See figure 3.

4. Specifications are based on an output of 10 volts.
