Introduction ADAM-3021

The ADAM-3021 is one of the most cost-effective, field-
configurable, isolation-based signal conditioners available for
protecting processed signals from harmful effects of ground
loovmotor miser anciather-electricatinterferenee, ADAM,_
3021 accepts high level analog signals at its input and
provides isolated voltage or current signals for its output.
The ADAM-3021 features the new optical isolation technique
providing 1000 Voc isolation with low power consumption

and extreme accuracy and stability within a wide range of
operating environments. ADAM-3021 has a maximum
±177.7pV/°C’temperature drift using only 0.8 W of power.
The ADAM-3021 offers superior performance at the lowest

The ADAM-3021 provides three-way isolation. The power
supply that drives the module’s input circuitry and output
circuitry is internally isolated, enabling it to offer true channel-to-channel isolation.

The ADAM-3021 is powered by a single +24 Voc. Power can
be easily connected from the adjacent modules, making the
wiring simple and easy to maintain. The ADAM-3021 can be
DIN-Rail mounted, and is built to operate in environments
with high humidity and wide temperature variation.
