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.
