SG-3071 Isolated Voltage Input/Output Module User’s Manual Introduction The SG-3071 is a voltage input to voltage or current output signal conditioning module. It has 1000Vdc three-way isolation for input, output and power. And can change the input/output range via internal configuration switches. The SG-3071 has an LED display to show whether the SG-3071 is functioning correctly and has two VRs (Zero, Span) to calibrate the input/output range accuracy.
