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
3000Vdc 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.
The bandwidth of the SG-3071 is typically 3KHz. It’s easy to mount the SG-3071 on a standard
DIN rail and can operate in environments with wide temperature range.

Configuration
The terminal wiring for the SG-3071 is shown in Figure A. Positive power terminals pins 7 and
9 are internally connected, as are negative pins 10 and 12. Power can be connected through
the adjacent modules, making wiring much easier. The SG-3071 uses a power input range of
10~30Vdc.
Table 1 shows the switch positions used to configure the input and output range.
The I/O configuration switches are located inside the module. And can be accessed by
removing the DIN-rail bracket covers by sliding them in the direction shown in Figure B.

Calibration Procedure
1. Refer to figure C to adjust the offset value.
(1) Connect pin7 to the +24Vdc connection and pin 10 to GND.
(2) Connect pin8 and pin 11 to the meter.
(3) Use wire to connect pins 1 and 2.

(4) Changing the SW1 and SW2 depends on your input/output range. Watch the value of
the meter and adjust the VR1 (ZERO) value to the minimum value of this range.
2. Refer to figure D to adjust the gain value.
(1) Connect pin7 to the +24Vdc connection and pin 10 to GND.
(2) Connect pin8 and pin 11 to the meter.
(3) Connect pins 1 and 2 to input source.
(4) Changing the SW1 and SW2 depends on your Input/Output range. Watch the value of
the meter and adjust the VR2 (SPAN) value to the maximum value of this range.
