Cards mix and match controller I/Os
Compact stackable modules interface with both low- and high-voltage peripherals.
Mosaic Industries has expanded its Wildcard series to add new 2 x 2.5in stackable modules to interface to both low or high voltage peripherals The Digital I/O Wildcard adds plenty of programmable digital I/O to a controller

Addon module embeds 24bit acquisition
Wildcard accepts low level signals directly from transducers, amplifies and conditions them, and converts them with 24bit resolution with no missing codes.
Card adds location-aware function to instruments
A miniature GPS card can fit on to a single-board computer and add location-aware functions to within an accuracy of 15m to board-based instruments and data-acquisition systems.
In addition to four dedicated digital inputs, up to 16 more channels can be configured for either input or output.
Each I/O line is also easily configured for pull-up, pull-down or tristate operation.
This allows systems designers to set the appropriate level of each I/O line in the interval between power-up and software initialisation.
Precoded software drivers allow users to configure the I/O lines as either inputs or outputs in groups of four, initialise, read from and write to the lines.
Output sink capability is sufficient to directly drive LEDs and other low power devices.
To interface high-voltage peripherals to an instrument or to drive a stepper motor, designers can use the Power I/O Wildcard.
This heavy-duty board provides eight high-current outputs and four high-voltage digital inputs.
Inputs and outputs are optically isolated to +/-2500V.
The current sinking outputs are intended to actuate high-current devices such as motors, relays, heaters and solenoids.
They can each sink 2A continuously and up to 10A intermittently while withstanding field voltages of 50V, and they are snub-diode protected against kickback from inductive loads.
Precoded device drivers provide high-level functions for turning on, turning off, and toggling the output lines, for reading back the state of the outputs, and for reading the inputs.
Up to eight different mix-and-match Wildcards can be stacked onto Mosaic's controllers for a unique combination of specialised I/O.
Other Wildcards include Ethernet, USB, octal 12bit D/A and 16bit A/D convertors, signal conditioning, a 24bit resolution analogue data acquisition subsystem, compact flash card mass memory interface, fast buffered RS232/485 dual UART, AC or DC solid state relays and more.
