The ADAM-4000 series is a set of intelligent sensor-to-computer interface analog I/O modules containing a built-in microprocessor. They are remotely controlled through a simple set of commands issued in ASCII format and transmitted in RS-485 protocol.
The 4000 series provide signal conditioning, isolation, ranging, A/D and D/A conversion, data comparison, and digital communication functions. Some modules provide digital I/O lines for controlling relays and TTL devices.

Wiring is simple using two wires to communicate with their controller or other RS-485 devices. ADAM-4000 modules use the EIA RS-485 communication protocol; the industry's most widely used bi-directional, balanced transmission line suitable for industrial environments.
Software Configuration and Calibration
ADAM analog I/O modules contain no pots or switches to set. By merely issuing a command from the host computer, you can change an analog input module to accept several ranges of voltage input, thermocouple input or RTD input.
Watchdog Timer
A watchdog timer supervisory function will automatically reset the ADAM modules in the event of system failure. Maintenance is thus simplified.
