Introduction
ADAM-3016 is a DIN rail-mounted strain gauge input signal conditioning module
with 1000 VDC 3-way isolation between input, output and power. The switch con-
figurable input and output offers flexible, wide ranging capability for strain gauge.
ADAM-3016 is equipped with a power LED to monitor the line power and a DC-to-
DC converter status and 3 VR (ZERO, SPAN, EXCI) to calibrate input/output
range and excitation voltage.
The ADAM-3016 features three-way isolation. The power supply that drives the
module’s input circuitry and output circuitry is internally isolated, enabling
ADAM-3016 to offer true channel-to-channel isolation.
ADAM-3016’s input bandwidth is typically 2.4 kHz. The ADAM-3016 is powered
by a single +24VDC input. Power can be easily connected from the adjacent
modules, making the wiring simple and easy to maintain. The ADAM-3016 can
be mounted on a DIN rail and operate in environments with high humidity and
wide temperature variation.

Configuration
Figure 1 shows the terminal wiring of ADAM-3016. Positive power terminals 9
and 7 are internally connected, as are negative terminals 12 and 10. Power can
be connected through the adjacent modules, making wiring much easier.
ADAM-3016 uses single +24 VDC. Table 1 and table 2 show the switch positions
to configure input and output range. The I/O configuration switches are located
insidethe module. Toreach theswitches, youneed toremove theDIN-rail bracket
by sliding it down.

Calibration for input/output
1. Disconnect power and set the input range (SW2) and output range (SW1)
to the desired setting, then apply the power.
**Define the following variables for calibration use.
--Low_cali_input = Min_input + Full Scalar Input * 0.05;
--High_cali_input = Max_input - Full Scalar Input * 0.05;
--Low_cali_output = Min_output + Full Scalar Output * 0.05;
--High_cali_output = Max_output - Full Scalar Output * 0.05;
2. Input the Low_cali_input signal;read the Low_real_output signal;
3. Input the High_cali_input signal;read the High_real_output signal;
4. Adjust variable resistor of SPAN and repeat step 2 & 3 to meet the following
condition
(High_cali_output + Low_cali_output) = (Low_real_output + High_real_output)----eq1

5. Adjust variable resistor of ZERO and repeat step 2 & 3 to meet the following
condition
Low_real_output = Low_cali_output----eq2
High_real_output = High_cali_output----eq3
6. If eq2, eq3 fail to meet your requirements, repeat step 4,5 until success in
step 5
Calibration for excitation voltage
1. Disconnect excitation voltage from gauge (for safety)
2. Adjust variable resistor of EXCI according to your needs
3. Disconnect power and apply excitation voltage to gauge, then apply the
power.
4. Finely tune excitation voltage according to your needs as in step 2
