SG-3016 Isolated Strain Gauge Input Module
User’s Manual
Introduction
The SG-3016 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-3016 has an LED display to show whether the SG-3016 is functioning correctly and
has three VRs (Zero, Span, Exci) to calibrate the input/output range accuracy.
The bandwidth of the SG-3016 is typically 600Hz. It’s easy to mount the SG-3016 on a
standard DIN rail and can operate in environments with wide temperature range.

The terminal wiring for the SG-3016 is shown in Figure A. Positive power terminals pin’s 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-3016 uses a power input range of
10~30Vdc.
Table 1 and table 2 show 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 and connect 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 VR2 (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 and connect 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 VR3 (SPAN) value to the maximum value of this range.
3. Refer to figure E to adjust the excitation voltage value.
(1) Connect pin7 to the +24Vdc and connect pin 10 to GND.
(2) Connect pins 4 and 6 or pins 5 and 6 to the meter.
(3) Watch the value of the meter and adjust the VR1 (EXCI) value to the 1~10Vdc of this
range.
※ The default value is 10Vdc ※
