Sensor-to-computer interface units

December 2006 Operator Interfaces, Switches & Relays

Advantech's ADAM-4000 series modules are compact, versatile sensor-to-computer interface units designed for reliable operation in harsh environments. Their built-in microprocessors, encased in rugged industrial grade plastic, independently provide intelligent signal conditioning, analog I/O, digital I/O, data display and RS485 communication.

ADAM-4000 modules accommodate multiple types and ranges of analog input. Both type and range can be remotely selected by issuing commands from the host computer. One type of module satisfies different tasks, simplifying design and maintenance. A single type of module can handle the measurement needs of an entire plant.

A watchdog timer automatically resets the modules if required, and since all modules are remotely configured by the host computer, physical adjustments are unnecessary. Only two wires are required to allow the modules to communicate with their controlling host computer over a multidrop RS485 network.

A standalone control solution is made possible when the ADAM-4000 modules are controlled by the ADAM-4500 or ADAM-4501 PC-based communication controller. These controllers allow users to download an application, written in a high-level programming language, into its Flash ROM, allowing customisation of the task.

The ADAM-4000 modules may be DIN-rail, panel or piggyback mounted, and signal connections are made through plug-in screw terminal blocks ensuring simple installation, modification and maintenance. Any controller using the Modbus/RTU standard can be integrated as part of an ADAM-4000 control system.

Advantech is represented locally by ProMicro.
