1. 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 3KHz It s easy to mount the SG 3016 on a standard DIN rail and can operate in environments with wide temperature range Specifications Voltage Specifications Electrical input 10mV x20mV x30mV 50mV x100mV Excitation voltage 1 10Vdc 20mA max Voltage output Bipolar 5V 10V Unipolar 0 5V 0 10V Output impedance 500 Current output Current 0 20mA Current load resistor 0 5000 Source General Three way isolation 3000Vdc Accuracy 0 1 of full range Bandwidth 1 2KHz typical 3dB Operation temperature range 25 C 75 C Storage temperature range 30 C 85 C Supply Voltage Input Range 10 30Vdc Consumption 1 44W voltage output 1 74W current output Configuration 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 module2. Vdc connection and pin 10 to GND 2 3 Connect pins 1 and 2 to input source 4 Connect pin8 and pin 11 to the meter 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 connection and 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 X The default value is 10Vdc 3x Block Diagram Isolation Amplifier Vin Dimensions Units mm 24 5 am 102 0
