Simple configuration, easy programming and supported by major DA & C packages - these are just a few reasons to use Advantech's ADAM 4000 modules.

The ADAM-4052 provides eight digital input channels: six fully independent isolated channels and two isolated channels with a common ground. All have 5000RMS isolation to prevent ground loop effects and limit the chance of damage from power surges on the input lines.

You can use any high-level language with ASCII-based string functions (such as C, Pascal or BASIC) to communicate with ADAM modules or process their data. For example, the command and response for an analog input module would be: COMMAND: #5, RESPONSE: > 4.834. This command requests the data stored by the module with address 05 (Hex). The module responds with the value 4.834 V.

ADAM's built in checksum feature ensures data integrity by detecting communication errors. This feature adds two checksum characters to every command or response string that enable you to verify that the message received is exactly the same as the message sent.

Easy-to-use menu-driven utility software make configuration and calibration a snap. Its terminal emulation program lets you easily read from and write to ADAM modules. Writing application programs with this software (ADAMView) is simple, you can learn the basics in just a few minutes.
