June 14, 2007 - Mosaic Industries has expanded its Wildcard series to add new 2” x 2.5” stackable modules to interface to both low or high voltage peripherals.
The Digital I/O Wildcard adds plenty of programmable digital I/O to your controller. In addition to 4 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 tri-state operation. This allows you to set the appropriate level of each I/O line in the interval between power-up and software initialization. Pre-coded software drivers allow you to configure the I/O lines as either inputs or outputs in groups of four, initialize, 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 your instrument or to drive a stepper motor, you 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 ±2500 volts. The current sinking outputs are intended to actuate high-current devices such as motors, relays, heaters and solenoids. They can each sink 2 A continuously and up to 10 A intermittently while withstanding field voltages of 50 volts, 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 8 different mix-and-match Wildcards can be stacked onto Mosaic’s controllers for a unique combination of specialized I/O. Other Wildcards include Ethernet, USB, octal 12-bit D/A and 16-bit A/D converters, signal conditioning, a 24-bit resolution analog data acquisition subsystem, compact flash card mass memory interface, fast buffered RS232/485 dual UART, AC or DC solid state relays and more.
