SG-3081 Isolated Current Input / Output Module
User’s Manual
Introduction
The SG-3081 is a current input to voltage or current output signal conditioning module. It has
1000Vdc three-way isolation for input, output and power. And it also can change the
input/output range via internal configuration switches.
The SG-3081 has an LED display to show whether the SG-3081 is functioning correctly and
has two VRs (Zero, Span) to calibrate the input/output range accuracy.
The bandwidth of the SG-3081 is typically 3KHz. It’s easy to mount the SG-3081 on a standard
DIN rail and can operate in environments with wide temperature range.
