Overview - Advantech ADAM 4000 Series User Manual

Introduction

1.1 Overview

The ADAM Series is a set of intelligent sensor-to-computer interface
modules containing built-in microprocessor. They are remotely controlled
through a simple set of commands issued in ASCII format and transmitted
in RS-485 protocol. They 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.
Software Configuration and Calibration
ADAM 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. All the module's configuration parameters including I/O address,
speed, parity, HI and LO alarm, calibration parameters settings may be set
remotely. Remote configuration can be done by using either the provided
menu-based software or the command set's configuration and calibration
commands.
By storing configuration and calibration parameters in a nonvolatile
EEPROM, modules are able to retain these parameters in case of power
failure.
Watchdog Timer
A watchdog timer supervisory function will automatically reset the ADAM
modules in the event of system failure. Maintenance is thus simplified.
Power Requirements
Although the modules are designed for standard industrial unregulated 24
V power supply , they accept any power unit that supplies power within
DC
the range of +10 to +30 V
V peak-to-peak, and the immediate ripple voltage should be maintained
between +10 and +30 V
