Signal conditioning modules

July 2005 Electrical Power & Protection

The ADAM-3000 Series are cost-efficient, field configurable, isolation-based, signal conditioners. The modules are easily installed to protect instruments and process signals from the harmful effects of ground loops, motor noise, and other electrical interferences.

Featuring optical isolation technology, the modules provide three-way (input/output/power) 1000 V d.c. isolation. Optical isolation provides accuracy and stability over a wide range of operations at minimal power consumption.

The input/output range for the ADAM-3000 modules can be configured through switches located inside the module. The modules accept voltage, current, thermocouple or RTD as input, and pass voltage or current as output.

Thermocouple inputs are handled by the built-in input thermocouple linearisation circuitry and a cold junction compensation function. These ensure accurate temperature measurement and accurate conversion of information to the voltage or current output.

The ADAM-3000 modules use a 24 V d.c. power rail, which can be acquired from adjacent modules, greatly simplifying wiring and maintenance. The I/O configuration switches are located inside the modules. To reach the switches, one removes the modules from the DIN-rail bracket by sliding the modules downward.

The modules are easily mounted on a DIN-rail, and signal wires can be connected through screw terminals. The screw terminals and input/output configuration switches are built inside the industrial grade plastic casing. With simple two-wire input/output cables, wiring is easy and reliable in harsh industrial environments.

Applications include:

* Signal isolation.

* Signal transmitters.

* Thermocouple/RTD/strain gauge measurements.

* Signal amplifiers.

* Noise filtering.
