Available in several configurations, each Multi-I/O board can add up to 8 channels of 12 bit A/D, 4 channels of 12 bit D/A, 8 relay output drivers and 2 UARTs. If more I/O is required, several boards can be added to the system using 10 pin IDC style ribbon cables. A driver library with functions callable from C or QuickBASIC and example programs are available to eliminate the hassle of programming devices on a serial bus.

Serial/Parallel - Flashlite 386Ex (84-0036) and Serial/ Parallel - LogicFlex (84-0033) peripheral boards both add 2 serial ports, while the 4Serial/Parallel (84-0039) adds 4 serial ports to the LogicFlex. On-chip FIFOs reduce the processor interrupt frequency (and CPU loading) during periods of heavy serial activity. PC compatible hardware allows the use of existing serial libraries and parallel port device drivers. The parallel port can also be used for additional bit I/O. Serial/Parallel Peripheral Kits (99-0014, 99-0032 or 99-0038) include the corresponding Serial/Parallel board, 2 board 40 pin bus cable, standoff kit, and users manual. A/D Upgrade Kit (99-0033) includes MAX197 A/D chip for 8 channels of 12-bit resolution.

The board features software-selectable input ranges of ±10V, ±5V, 0V to 10V, and 0V to 5V. Conversion time is 6µs. The basic A/D Converter board has ±16.5V input protection and unbalanced inputs. An enhanced version of the A/D board is also available. This board can be upgraded on a per-channel basis to provide balanced inputs with ±200V common mode rejection and ±500V common-mode and differential protection. The board also 84-0007 has screw terminal input connections and ±15V available for external signal 8 Channel A/D, conditioning. Enhanced with Clock The Burr-Brown INA117P high common-mode voltage difference amplifier is used on each channel of the enhanced A/D converter board to provide the increased common-mode and differential protection. Channels on the enhanced A/D converter board that have not been upgraded are still available for use as unbalanced inputs with ±16.5V input protection. Note: The Enhanced 8 Channel A/D board does not come with any INA117P amplifiers. These must be ordered separately. If you purchase an Enhanced A/D and INA117P amplifiers together, we can install the INA117 amplifiers and test the configured board as a system at your request. Versions Available 8 Channel A/D, Basic (84-0003) 8 Channel A/D, Basic with Clock (84-0006) 8 Channel A/D, Enhanced (84-0004) 8 Channel A/D, Enhanced with Clock (84-0007) A/D Peripheral Kits (99-0003, 99-0004, 99-0006, 99-0007) include the A/D board, 2 board 40 pin bus cable, shell and pins, standoff kit, and manual. 8 Channel Relay Output and Opto-Isolated Input Board This board has 8 relays and 8 opto-isolated inputs. The relays have 10 ampere, normally open contacts. The opto-isolated inputs accept 3-24VAC or DC and will withstand a momentary short to 120VAC. Both the relay contacts and the opto- isolated inputs are terminated with industrial-grade screw connections. 84-0002 Relay I/O Peripheral Kit (99-0001) include the Relay I/O board, 2 board 8 Channel 40 pin bus cable, standoff kit, and manual.
