Part of the family of I/O expansion
modules for the PicoServ miniature web server system, the
Digital I/O Expansion
Module provides a simple means of interfacing 8 digital input
and 8 digital output signals to the web server or SMS modules.
Real-world input or output signals connected to the expansion
module are easily displayed or changed in any web browser using
only simple HTML commands.
The digital I/O module stacks directly onto the
PicoServ server module to provide a ‘no development’ route to
providing eight logic level digital inputs, four logic level
digital outputs and four relay isolated outputs.
Additionally all digital inputs can be assigned to a
time-qualified alarm status. Up to eight digital I/O modules can
be configured in one system, providing up to 64 inputs and
outputs.
The digital I/O module has over 60 parameters which are used for
module configuration or to exchange data between the module and
a web browser via the PicoServ web server module, or a GSM
handset via the SMS gateway module.
In addition to the standard module functions, Compulogic are
able to provide bespoke firmware to accommodate particular
customer requirements, for example automatically changing output
states based on measured input values.
