RS-485 I/O Modules
Advantech ADAM-4000 Series

Compact and versatile sensor-to-computer interface units.

The ADAM 4000 series modules use the EIA RS-485 communication protocol, the industry's most widely used bi-directional, balanced transmission line standard. It lets the ADAM 4000 series modules transmit and receive data at high rates over long distances. The ADAM-5000/485 system is a data acquisition and control system that communicates with a network master over a twisted-pair, multi-drop RS-485 network.

Their built-in microprocessors, encased in rugged industrial grade plastic, independently provide intelligent signal conditioning, analog I/O, digital I/O, data display and RS-485 communication. The ADAM-4000 series can be categories into three groups: controllers, communication modules, and I/O modules.

ADAM-4000 series modules need just two wires to communicate with their controlling host computer over a multidrop RS-485 network. Their ASCII-based command/ response protocol ensures compatibility with virtually any computer system.

You can easily mount modules on a DIN-rail, a panel or modules can piggyback on top of each other. You make signal connections through plug-in screw-terminal blocks, ensuring simple installation, modification and maintenance.
